Builder Gel for Nails Challengel – hard, HEMA-free, ideal for nail extensions

Challengel is a hard builder gel designed for those who want to combine fast work with a strong, long-lasting finish. Perfect for nail extensions on forms, strengthening the natural nail plate, and no-file techniques.

Its light consistency means the gel does not drag behind the brush during application, levels quickly and evenly, and minimizes the need for filing. Its high hardness allows you to pinch a stable tunnel that does not expand during wear. The styling lasts up to 5 weeks.
