I find Safeway 4l vanilla ice cream tubs to be very handy, for everything
from mixing small quantities of plaster, to acting as mini stacking boxes.
They are polypropylene, and quite robust, being stackable many high
even with lots of stuff in.
However, I'm about through my supply, and apart from the fact that safeway
are now Morrisons and they no longer do the ice cream, eating my way through
a few dozen 4l tubs of ice cream would not do wonders for my already
not-too-elfin figure.
Can anyone suggest a source?
