Loved these, but mine dried up after 2 days!

I was a TA in college and my prof gave us these pens for grading papers, and that's when the love affair with these pens started.

I ordered these hoping to rekindle this romance and was very happy...at least at first.  Yes they changed the design a bit, but they were pretty much the same, awesome pens.  After 2 days, however, the ink started to fail on some of the pens.  The black is now more like a grey after only 2 days.  Only 2 days!  And without much use.  I'd send them back if I hadn't torn the packaging open like a starving grizzly bear after some meat.

I still love these pens, but I think I got a bad batch.

Loved these initially, but either they dry out super quickly or the color becomes so liquidy that when you write with them it just drips down.

I used these one time, loved them. Next time I went to use them 2 of them were dried out and almost all of the rest significantly lost their color since the last time. Just disappointing.

I loved these when I first received them. They were very comfortable but after 2 wears at the gym, they ripped! There might possibly be good and bad batches due to the mixed reviews... if so, I definitely got the bad ones.

One of the pens was dry already upon receipt, another dried up within a day. The colors are amazing and I love the white more than anything, but a bit disappointed by low ink reserves or poor craftsmanship or whatever causes pens to dry up before you even use them.

The colors are beautiful and I enjoy how they write but! After 1 use of every color they dryed out! I cant write more then one sentence without a new pen dyeing on me! Please don't buy

These were fun for my son for about a day. Then they dried up. For the price I won't complain though. I used them as a stocking stuffer.

Well, I would have given these five stars except for the fact that they cannot be reused. I bought them to keep trays of hors d'oeuvres cold at an outdoor wedding. They worked perfectly for that. After, I left them to dry out (as suggested by some other users,) but they never did. Finally put them outside on a patio table to see if the sun would help to dry them out (this was after almost two months) and they not only did not dry and flatten out, but some sticky goo seeped out of them. I am having to throw them all out. I loved the way they worked and if the water could be removed and they could be stored and used again, I would buy them in a heart beat. Great product for one time use or if you plan to keep them frozen.

They fit perfectly until I dried them too long (not intentionally) in the drier.  I threw these in with a load to dry on medium heat intending on pulling them out in 15 mins but forgot - I even set a timer but was not near it when it went off.  They are now a little tight and too short, I think I can still wear them and maybe they will stretch some.

I loved these.  For the two days I got to use them.
I'm a smaller female, with a size 8 boot, and these fit snug inside.

So snug, in fact, that upon removal one snapped at the bend point and is no longer usable.

So be careful.  But it is nice to have dry toasty shoes in the morning!
Buying a replacement, when I can find a smaller size option.

The slippers are so comfortable. I absolutely love them. However, 2 days after buying them, water was spilled on them from doing dishes. One slipper didn't absorb the water. The other slipper did and it stained. Bad. My husband took the shoes to a repair place. They cleaned and treated the slippers. Looked brand new. A few days later, water dripped on them again while doing dishes. One shoe didn't absorb the water. The other did - Now they're stained, again.

When new these paints are awesome! Vibrant colors and they spread and blend wonderfully with a blender or baby wipe. But they dry up very quickly and become unusable. Adding water does not work to revive them. Ive thrown away several nearly full jars already.

I use these at work. They're awesome to write with but dry out so quickly.

I like the ultra fine part, but all of them DRIED off after 3 months of purchase!!!!! =(
I didn't even use that many times, and had the cap on.

I fell in love with these the first time I used them. It was my first time using paint pens and they were just awesome. But when I went to use them a second time, one was already dried up and another was nearly there. (Yes, the caps were on tight.) I still have a few that work well, but I'm disappointed I wasn't able to use them for more projects.

I really wanted to give these 5 stars. I love the pens. But I find that the refills skip and dry out after about a week. I have tried sealing the containers once I open them with tape. However, that really doesn't seem to be the problem as I notice that I have had the same problems with unopened packs. Perhaps they sit around too long after being packed, I don't know.
I am using black refills. Perhaps the blue are better, but my line of work requires black ink.
