Review (1/5): Don't waste your money...
I'm in no way a nail professional, however these brushes are junk when trying to use with builder gel. If you can buy cheap from China, wait the 20 years for them to be delivered. At least you get what you pay for. I paid $8 so not worth it! I winded up buying new brushes from Alpha Brushes they were $5 a piece but works way better then these.
