These large stones are designed to enable children to have sensory experiences by experimenting with the raised and indented shapes and patterns. Cast from a durable mix of resin and real stone, 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). Age 18mths+.
