These unique paints can be used in the tub to create temporary art, practice letters and numbers as well as many other uses. Your child will enjoy these washable paint markers are designed for tub and tile use, but will wash out of towels and off of tile, vinyl, fiberglass, grout and any other articles that the paint may come into contact with. The patented, spring-valve applicator allows easy, controlled application of the paint, eliminating waste, mess and leaks. When the markers are dropped in the tub, they will neither leak into the water, nor allow water into the bottles. Choose from six different colors and engage in imaginative play.
