Gu puddings. The cold ones are delicious, and not too large. Big enough to satisfy, but one is plenty. The hot ones are horrible, but we aren't concerned with those right now.
Anyway, each pudding comes in a little glass dish 8cm wide and 4cm deep. It's a nice quality item that bugs me because you chuck them in the recycling after one use. OK, glass recycles well, but it seems so wasteful.
It occured to me that a couple of these would be useful on the modelling board as somewhere to put little bits while working. A safe haven for screws and small components.
I'm not alone in this - now I know what I'm looking for, I've seen at least two on the TV show The Repair Shop. And another on the jewellery making competition All That Glitters. At first I wasn't sure, but have now taken to peering closely at the screen every time a glass pot appears. Yes, I am weird.
