A hands-on squishy gel experience! Encourages visual processing and sensory stimulation for all ages. Invite sensory-seeking kids to step, sit or jump on the tiles and watch the colours ooze. Even young children can push the gel around with their hands. Place several on the ground to create a colourful floor mat or walking path. Each 50cm x 50cm (19-1/2" x 19-1/2") tile holds up to 150lbs. Acrylic tile with wood base. Ages 1+. Set of 4 includes one of each colour (blue, green, purple, and orange).
