I saw sandwich-type nail forms on TikTok and wanted to try them, so I bought some on Amazon. These are reusable nail forms that you can take off with a click, so I'm selling the ones that don't fit my nails or that I have extras of. I keep the ones I use in a separate case, so these are unused. This is a set of 15 sizes, from size 0 to 14, with 4 sets of each size (for both hands x 2), packaged together in a zippered bag. The size numbers are stamped on the tips themselves, so please use the same number tips together as a set. (You can use them in the traditional nail form style, using only the top or bottom part, instead of the sandwich method.) You can use strong extension gels like polygel, builder gel, or sculpting gel with these. I will wrap them in bubble wrap and ship them via Yu-Packet Post Mini.
