Only for water based markers
587997
This book is useless to me as it only covers water based markers, and I use permanent markers such as Copic. I think that should have been clearer in the description.

These markers don't look like watercolor at all. They are nice markers but they do not have a soft water color look to them. Bought as a gift - pretty disappointed.

Not to be used to test pool salinity levels for chlorinator.  Does not give accurate levels for this type of use.

I wish I had done more research before I got these.  They are not good for alcohol markers.  They smudge.  Oh well, I will find another use for them.

I ordered the copic multiliner instead, and those are supposed to be good for alcohol markers.

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.

Not sure why this is marketed as watercolor paper. It doesn't work well with water-- it warps and tears very easily.

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.

I had to use several small pieces to write in a board. The crayons are not bright as liquid markers. Threw it away and got liquid markers.

Dried out markers.  Don't waste your money.

Marker stains dome if not washed off after a few hours & also really eats up the batteries. Marker dried out after 2 uses and sitting in the garage because no more markers to replace them.

Virtually ran out of marker ink after just a few applications.  Terrible method to get ink to flow onto project and then it comes out in globs.  DONT BUY IT.

These markers draw on metallic but dry like a regular marker. Waste of money. Just buy regular markers.

The shipping was great though and it came brand new

I use gel pens, markers (both alcohol and water based), and colored pencils in my sketch books, and while this sketch book worked well for my gel pens and my colored pencils is feathered a lot when I used any type of marker (including lining pens that i've never had bleed or feather on me). I also found it a bit difficult to blend my markers when using this. My copic markers bled through the page (although i knew they would, so this is more of a warning for others). Over all I personally wouldn't purchase this again, because I use markers a lot, but if you're using a different form of media this may be the sketch book for you.

Don't buy these. The ink is so translucent it's almost unreadable, and erasing it leaves objectionable stains. I thought I permanently stained my white board with these when it didn't wipe off. I tried Expo's cleaning solvent, water, soap, and Windex. None of them worked, but I was able to clean it with 70% isopropyl alcohol (ordinary rubbing alcohol). It finally removed all traces of these markers. If you already stained your board try it.

Ordinary Expo markers are good:

It's hard to believe they'd even sell these.

Though these labels are decorative, the marker rubs off too easily.  They are useless if you want to label your product and be able to read your writing after a day.  Especially not good for essential oil blends.

I bought these markers to use on a 'sandwich' board that is on the sidewalk.  These are good markers..... except....  Let me preface this statement by explaining why I was looking for markers to begin with.  When I bought my sandwich board it came with makers.  They were great.  Sometimes they had a blob that I needed to fix which was annoying, but overall the 'cheap' makers were good.  When it rained and the board was getting wet from splashes or actual rain the markers never ran.  My sister sent me some liquid chalk markers telling me they were really good (read 'expensive').  They weren't.  They didn't write well and when it rained the words written by the markers ran.  I tolerated them because why throw away money, even if it wasn't mine.  I waited to see how these markers would do overall but especially when it rained.  I am sad to report that these markers run worse than the ones my sister sent.  I have the sandwich board covered by an overhang, but just the humidity from the rain, the splashes from the rain drops caused these markers to run.  It's disappointing too because they wrote well, the colors are bright and I have the option to switch tips.  While markers that run when wet may not be an important thing for everyone, I don't change my sign daily.  I am a yarn store and I put quotes or sayings on the board, motivational type things.  Today's was "Being creative is not a hobby, it's a way of life"  and I've already had to re-write the board two days this week (I'm open Tues. thru Sat.)
Now you may be asking, "why did I give it 5 stars if I'm not completely happy?"  Good question.  The reason is this: These are good markers.  They don't blob and the color doesn't separate.  But most important the CEO of Superior Markers contacted me throughout the purchasing process, to let me know they received the order, that it was on the way and that I received them and what did I think of them.  I didn't respond right away because I wanted to see how they measured up.  I wrote almost exactly what I wrote here and complained about them running.  Her response was, 1.) information of what I was looking for in a marker, 2.) markers brands that did what I wanted it to, 3.) other suggestions to use the markers and 4.) offered a refund.  Seriously?  Someone pinch me.  Did I just receive excellent customer service?  I am so pleasantly surprised by this.  It deserved the 5 stars.  Because they're good AND the customer service.  And seriously why would I deduct stars because I didn't know what kind of markers I needed?  Right.  Exactly.

I didn't get to try these markers right away, but should have at least looked at them.  Some markers have little color left in them.  One doesn't have the felt tip.  I mean it is completely gone.  The worst part is it's the black marker which I would use a lot.  One other marker, the brown one, has no color.  It's completely dried out.  The yellow barely will make a mark.  I gave it three stars because the other colors do have good color.
