Washable gel crayons (Glass colors) : Board, Window, Tub use available

This crayon is very versatile and has many uses. It can be used to draw and play on glass, such as board, windows, tub as well as on paper. It can also be used on dry-erase boards and wiped clean with a wet tissue. It even has a watercolor effect when used with a wet brush.

One of the great advantages of this crayon is that it is washable. It's perfect for outdoor and indoor play during the summer and drawing on windows adds a fun twist to doodling. Many glass pens are not washable and are not suitable for children, but this multi-purpose crayon is perfect for both children and parents to enjoy with peace of mind.
