Prototype. Part of a flexible new range of mini stacking containers, currently under development. Rounded corners allow units to be carried comfortably in a bag, or push-fit, flush, into storage racks or drawer organiser systems. 2cm high, two units can be stored as a 4cm×4cm block. A smaller opening than the standard FingerTray, can be stored vertically with less risk of spilling. 0.75mm wall thickness, suitable for WSF or silver metal.
