Review on JASSINS 50 Pcs Nail Swatch Sticks with Ring: Clear fan-shaped polish practice display for nail art professionals by Donna Hoff

Great chopsticks, key ring Easy to use but you shouldn't use them when you need to clean. They are made of ABS or similar plastic that is not safe to use with acetone. I did a test first so I knew how careful to apply the product and the acetone caused some problems. I soaked a cotton pad in acetone and quickly rubbed half of a nail with it like I was preparing a natural nail for application and it clouded and softened a little. If you can apply the polish cleanly, or perhaps very quickly with little to no acetone, they will work for you. But if you find it difficult to stay on your nails and need sharp edges, I would try a different brand of Swatch Sticks.
