This stuff works great!!
I had started painting during Covid out of boredom, hoping that my mom's talent had been passed on down to me. When things started to get back to "normal" (as if they ever really will, lol), the unfinished painting sat on the easel for over 2 years. Now I am scheduled for rotator cuff and bicep surgery on my dominant arm and I am bound and determined to finish the painting before surgery. Except the paints had become unworkable. Not really expecting it to work, I bought this thinner and, lo and behold, even the most gunky, dried up colors are workable again!! I was so amazed and grateful! I would buy again, although it will be many months until I can paint again after surgery.

BEAUTIFUL PAPER
Beautiful paper - it's the user that needs work! The ink flows well and I love the bright results. I did notice some staining and the flatness of some colors when blended (probably user error). Now I just need to learn how to properly work with the alcohol ink.

Not effective
The product thinned clumping acylic paint much like adding water. I thought it would do a better job helping to restore the original consistency. I wouln't purchase again.

Excellent Thinner for Paint By Number Kit
I bought this to help with some of the paint pots I receive in paint by number kits because sometimes the paint is super thick or hard to paint with. This helps a TON to help the paint thin down and doesn't effect the quality. Highly recommend!
