IDO3D Ultra - 4 Pen Set - Outer Space, Create 3D Arts and Crafts, Drawing and Painting Supplies

Reasonable price & arrived quickly. Was a present for my daughter & she loved it (age 11). She worked out how to use it quickly & enjoyed using it.

This smells like bad quality gel nail polish and I suppose the chemical composition is the same. The ink does not solidify well, a mess is unavoidable.
