Plastimo Wood Ring From £3.46

I have two of these in my galley. They're solid in design, but after a few years of use both of them have cracked, but they're very easy to neatly glue back together, so no big deal it's only a £2 piece of teak! The 39mm version also doubles up as a 1-portion spaghetti measuring device. Size up to 45mm if you have hungry sailors on board.
