Gel colors only come in 2.5g. However, KOKOIST color gels are very pigmented so a little goes a long way.  You should be able to apply about 40 sets of short nails with 2.5 grams.

KOKOIST gels are free of animal-derived ingredients and are not tested on animals at any level of production.

Wrap the nails with acetone for 10 minutes after filing down the product as much as possible. Repeat the process if necessary.

Our colors are designed for 1 to 2 THIN coats. The 2.5g jar is good for about 40 sets on a short to medium length nails.

It's basically reusing the clear foundation(Base Coat) underneath the color & top coat instead of soaking off the product for a new set. When you are ready for a fill, file off the top coat and color, leave the clear foundation on the nails. Backfill with Platinum Bond Duo and Builder Gel(if needed) after prepping the cuticles and blending the existing gel to the exposed nail bed.

Our base gel will not peal off like a sticker. If this happened to you, there may have a preparation problem such as oil or any other moisturizing product that remained on the nails surface(please wipe your nails thoroughly with alcohol before applying the gel) or you may have applied the duo too thin or too thick.
