Cast from resin, they can be used on their own or as part of a wider sensory experience incorporating messy play.
Each stone in this set of eight measures 75mm and include four raised/bumpy designs (circles, dots, wavy lines, and a grid) and four indented/hollow designs (circles, lines, zigzags, and a spiral).
