Contents: 400 Ecko shapes (250 x small triangle, 100 x trapezoid, 50 x large triangle), 6 x frames with a diameter of 11 cm.
Ecko stones can be used to create a variety of imaginative shapes and patterns.
The stones look particularly beautiful in the light or on a light table.
All shapes can be combined with each other in the laying frames.
By placing stones, children practice understanding shapes and sizes and stimulate their creativity.
The laying frames have a pronounced curvature so that the stones are held firmly in the frame under tension.
This means that the last stones are placed under pressure.
