Ten different wooden cylinders with tactile surfaces and an accompanying solid wood shelf with the same reliefs.

A challenge for visually impaired and blind people because the tactile contrasts (differences in tactile perception) are less clear. But if a child has already progressed and it is also very important for that child in daily practice to be able to perceive and distinguish between different structures by touch, then this version is suitable for that.

The visual differences are also minimal, which is an additional challenge for the visually impaired.

Initially with open eyes, later possibly blindfolded, your child can place the cylinders one by one in the correct place on the shelf.

The surfaces from left to right: green: felt, gray: plastic net, brown: cork, brown: corrugated cardboard, brown: fine sandpaper, white: foam rubber, white: thin packaging foam, white: thin packaging foam, brown: lacquered wood, orange: glossy paper.

The shelf and cylinders are made of unpainted wood.
