Our Round Soothing Sand Window is a little piece of eye candy paradise for your desk, classroom, home . . . anywhere! The mesmerizing scenery inside this interactive sand window changes every time you flip it over! You'll love creating sparkling patterns, rolling waves, snow-capped mountains that morph into avalanches, rushing waterfalls, and so much more. This beautiful visual self regulation tool is wonderfully calming and soothing, but is not a toy for young children (as the glass window will crack or break if dropped/hit). Measures 8” across. Designed for ages 10-adults.
