coincidentally, someone bought us some nice loose tea in small cannisters recently. we don't own a teapot and didn't fancy just putting a spoonful in a mug with hot water so have been looking for an alternative. in m & s yesterday found the very thing, a small hinged metal mesh thingy which takes a teaspoon of tea leaves and snaps shut allowing you to put it in the cup with boiling water, but with no tea leaves escaping.
it's just the job and cost £2.50.
something like this:
