Modular Stackable Gel Polish Rack – 6 Bottles per Level

Keep your gel polish collection organized, visible and easy to access with this compact modular storage rack.

Each level holds six bottles in a single row, making efficient use of space without hiding the labels or colour indicators. The open-front design allows the bottles to be gripped and removed easily, while the individual recesses keep them securely positioned.

The rack can be expanded vertically as your collection grows. Simply print additional bottom sections and finish the stack with the included top section. Integrated alignment pins and matching holes keep the levels correctly positioned and create a stable, clean-looking storage system.
