The Pythagoras Shelves shelf 3-pack from Swedish Maze lets you create your own unique shelf system. The shelf is part of the Pythagoras shelf system designed by Gustav Rosén. The shelves are mounted with, and have pre-drilled holes adapted for, Pythagoras Brackets which are sold separately. The three shelves can be placed in a row, at any height or independently of each other. Use these shelves with Pythagoras' box for a coherent look and a shelf that meets your needs.
