Click is a Polyurethane shelf support. Plastic is often used for connection parts or construction games. Because it can be flexible, plastic is easy to clip or click, and to take apart. In another hand, wood, in its industrial form, comes most of the time in plank shape. The thicknesses of plywood planks are standard.
Click is a simple and playful way of building the shelf you need. No glue, no screw!
The process is very simple:
1)Go to any make-it-yourself store, and buy 9mm plywood, the width and the length you need. Not more, not less!
2)Click the plastic block into the wooden plank.
3)Hang the shelf on the wall!
You are done, enjoy your shelf!
