A single shelving unit has a fixed bottom shelf and interchangeable top shelf. The top shelf can be positioned at varying heights and used to link multiple units to create more storage space.

The shelves are held in place with removable nylon dowel pins. Once the shelf is lowered to the desired height the pins become recessed underneath fixing them into position. 

Constructed from 15mm plywood treated with a hardwax oil finish. The legs are solid beech dowel treated with a clear lacquer. Bracket pins are made from nylon dowel.
