On Monomer Polygel, the useful cards are Nail Art Kits. Check size, count, or format as printed before you compare price.
- Shade or undertone written on the listing, not only the swatch photo. Skip cards that only mention Polygel in the title.
- Finish and format (cream, powder, liquid, stick) versus how you will wear it.
- Full size versus mini, and whether an applicator is in the box, as listed for Nail Art Kits.
If a card is not clearly Nail Art Kits, skip it. On the rest, compare the nail art kits spec, then prices and ratings.
