Consider just buying window markers
598192
The almost 12"x14" box holds 12 window markers (which are different than Crayola window crayons), a clear plexiglass drawing rectangle with smooth, curved edges, a plastic stand to hold the plexiglass, and a paper with perforated stencil shapes. And, of course, the idea book along with this solid cardboard carrying case.

It's all ok for what it is, but before buying, consider if you need this $20 something big box or just a set of window markers and separate heavy duty (yet thin for thick marker point) stencils. The stencil sheet is flimsy and thin cardboard paper, the box takes up more space than necessary to protect plexiglass and plastic markers.

Unless you have no windows for artwork, consider the cheaper option of just window markers.  If this kit had a clear and obvious focus on geometric shapes for drawing and/or math, I'd reconsider.

The markers are so light and take so long to color and show up that my boys were pretty much over it after only 10 min. Very disappointed in this. Was hoping it would be a great playroom option and we could hang it on the wall but the markers are not very good quality.

I can only hope that the regular Color Explosion Glow Board works better than the Cars 2 version. The markers barely show up on the board as you're tracing, so it's hard to see what you're drawing. The effect is less than dazzling when you turn the board on. Unbelievable that I keep buying these Crayola products that promise so much and deliver so little. From now on, I'm sticking with their basic crayons -- the Twistables are awesome -- which are still the best out there.

This "re-writable" planner is hardly that.  Dry markers, including the one shipped with it, do not wipe off well at all.  Various labelled cleaners and elbow grease still leave ghost images.  Whatever brand I had before, I am going back to it!

First I could not get stickers off paper.  I though someone sent me a blank piece of paper.  The only good thing about this is it required windows to be clean.  I now have clean windows but stickers still fell off!!!

These markers must be very old!!  Out of the 1st 4 used, the ultra fine tip quickly dried out with very little use rendering the marker useless to me. The primary reason for paying the higher price is because of the ultra fine tip!! I needed a marker with this very fine tip. This is not it. Why do they sell junk like this? That costs us extra time to return it and then find a good seller.

These oil based markers make a mess - you can't really blend the colors and they take too long to dry.  I don't recommend them.  The water-based paint pens are so much better, although word is that Sharpie is dis-continuing water based paint pens - I don't understand why they would, be cause the water based pens are so popular and work just great for painting anything.  UNI POSCA water based paint pens are still available, though.  I recommend using those instead.

Copic Markers are just the same as the Magic Markers you can buy at Staples or Wal-Mart.
 Save your money.

I bought these instead of another large Crayola package for 2 main reasons.

1) The tray looked a little bit better than the Crayola box. The Crayola package is too snug and we can never get them all back in.
2) The color designations on each marker. For some reason the Crayola brand does not have the marker colors labeled.

Well, the tray is better than the Crayola box. Unfortunately, all the marker barrels are blank except for the brand name. This makes it very difficult to keep track of what colors you are using so you can go back later. Other reviews complained that it was annoying because the name wasn't on the cap, just the barrel. Now there's nothing. I don't even need "fancy" Crayola names like "Cornflower" and "Parrot Pink". Numbers like #134 or #B27 would be sufficient, but now it's 100% guesswork.

It's hard to find good, mid-grade markers. These seem to fit the bill, but without color designations I can never rate them higher.

Based upon other reviews, I purchased there for use in adult coloring books.  What a disappointment!  The markers leave a very streaky effect, and even though I used a very light hand with them, the tips fray something awful, leaving bits of felt on the picture being colored.  They may be fine for little kids to play with, but other than that, forget it.  Incidentally, after I purchased them I saw the exact same kind of markers at Dollar Tree in packs of 20, and in a tub of 100 for $6.99 at Hobby Lobby. (The latter has many duplicate colors.)

If you enjoy coloring, get the fine or ultra-fine Sharpie markers. They cost a bit more,  and the color selection isn't as wide, but the results are far superior to this junk.

Sure, it's a great marker and I recommend it, but don't buy it from here. It's WAY overpriced. Try Target or Walmart. It's easily 3 times as much as you would get it from a store.

Have to buy a new calendar - after writing all our family's December activities, I flip the page to start on January - complete bleed-through (sloooow buuuuurrrnnnn of frustration!)  My copy is impossible to use with markers!  You have to use pen or pencil - warning to others marker-Moms....
Also, just to test out the design, it is too wide - the thin paper corners flop over - fine if you like floppy-eared calendars.  I am going elsewhere for 2018.

The colors are nice, but the markers had very poor coverage on shiny smooth surfaces. The "ink" just sort of beads up and it takes a few coats. Bummer.

If I saved the packaging I would have returned these. The marker does not show up well on any material Ive tried and all wipes away too easily to be effective. Plastic disposable cups, traditional glass wine glasses and hard plastic cups.

These are satisfactory as a temporary window covering but they fade rapidly, their pleats get pretty tired, and putting them up is really, really annoying (although what should one expect from pleated paper with clips?). Also, their self-adhesive is woefully inadequate--I should've known since Amazon told me everyone purchases double stick tape with them.

The Quartet ReWritables Mini Dry-Erase Marker set is a great concept but poorly executed.

Pros:
None that I can think of...  Oh.  How about this:  The black marker writes dark enough that it can be read from across the room.  Whooo Hooo!
And, wow, I just thought of another one: The erasers work!  Stunning accolades, for sure.

Cons:
The yellow might as well be invisible, and the rest of the colors are too pale to be read from more than a few feet away. As I noted above, the only marker that can be read from a distance is the black.

The magnets are so weak that they are close to being useless.  I have a&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Quartet-ReWritables-Daily-Quick-List/dp/B003KGBGO0/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Quartet ReWritables Daily Quick List</a>&nbsp;on my refrigerator door, along with the black marker.  When the door is closed the marker slides down the door and drops onto the floor.  I tested the magnets on the other markers and they were just as bad. The only solution that I can see is to super-glue a decent magnet to the black marker.

Disappointing, to say the least.

Update, June 2014: Even after I glued the magnet to the black marker, I was still not happy with it.  Within a very short time the color in the marker faded, as if it was already running out of ink.  I ditched the set and replaced it with&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Low-Odor-Dry-Erase-Markers-Ultra-Fine-Point-Assorted-Colors-Set-of-8/dp/B00I8OBAOU/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Low-Odor Dry Erase Markers, Ultra-Fine Point, Assorted Colors, Set of 8</a>.

Such a disappointment!  My daughter and I had high hopes when we opened this.  There's a good sized, attractive mat.  I loved the way it rolled up for easy carrying and storage.  The mat has places to store the markers and the wiper.  We opened the markers and my daughter got down on the floor to get drawing.

"Mommy, the markers don't work!"

Sure enough, the markers are so pale that they are almost invisible.  It's pretty bad when the most visible color is the yellow marker - and even that was barely there.

My daughter tried.  She struggled with the markers, pressing harder, trying to get some color out of them.  She successfully used the wiper to remove the little color she created.

And then she gave up.

Until they fix the markers in this set, I cannot recommend!
