This is a modular Craft vinyl storage system. It can be mounted to any flat surface using the Wall Mounts that slot into any of the cutout sides of the Hex. When assembling you can omit the center of the 6 in a ring form to have a wider holder if needed.

I have tested the wall mount for compatibility on the Hexs but have not tested its mounting to the wall. The Holes are 5mm so most screws should work.
