Handy hint for paint storage

 Here’s a handy hint for you (in the UK at least). Steradent denture cleaning tablets come in plastic tubes, and the shelf display is an expanded polystyrene tray that is ideal for dropper bottle paints. They fit Army Painter (left), Vallejo (middle) and Humbrol (right) very nicely, tightly enough that you can stack them up and they're fairly stable.

Paint pot storage. Normal paint pot doesn't quite fit!

I always have a look in the supermarket to see if there is one empty that I can surreptitiously slip in my shopping bag.  Vitamin tablet tubes come in similar displays, but they’re usually vac-formed plastic trays that are shallower and often a bit too small for dropper bottles.  They do make handy painting pallets though!
