What are 'RUB Inserts for unpainted stuff'?
Trays that fit inside the tops of the boxes. Be warned that they stretch your box lids making them loose if you don’t use a tray.I have maybe two or three dozen RUBs, mainly 4l and 9l like fred. I use them for painted 15mm armies or sorting & storing stuff for future projects
The larger RUB's became hard to find near me (Chicago - US) but you can order from their website.
