10 Pcs Self-Adhesive Shelf Bracket Pegs Plastic L Shaped Cabinet Bracket Supports, 70 x 70mm

Two comments. They give you ten pieces. Each shelf unit needs 4 so why not 8 or 12 pieces. The price per uniit is rather high since I can only use 8 of them.

I like the fact that it is clear

Doesn’t hold up any item on a wall. And damages wall terribly at removal. Don’t purchase
