Sandbox with two see-through sides and two dark-grey sides. The see-through walls make this a completely different experience from the usual sandbox! Being able to see into the box gives ideas for new kinds of games. The wide seating boards on the edges make it comfortable for grown-ups to sit on. The edges are 470 mm high. Being small (1,730*1,720 mm), this box is suitable even for little urban parks. The dark grey sides match the rest of the Halo family of products.
