These guys stack and come with both a spout and a plug! Rounded for ease of holding, and they’re keyed so they don’t slide off one another easily when stacked.
The base is ~7cm across and ~16.5cm long. The standard height is ~10mm to the top of the tray (excluding the tabs) and the extra deep is ~18mm.
Price is per tray. Lids are optional – they are great for putting on the top tray of the stack or for covering up trays that aren’t currently stacked.
