Pill Bottle holders, they are sized for pill bottles which are still being used as such and still have labels on them and a base diameter of 32mm. they tapper slightly outwards at the top of the holder.
Equally useful for pill bottles that have bits and pieces of 3D printers etc. stored in them
Can't take decent shots without showing the label contents, hence top shots
Hope they are useful to someone else
