Wonderfully Deco 1930s/40s strainer - for tea, or whatever else you'd like to strain.
Made of plastic, from an era when plastic was a novelty and a saviour - hygienic, strong, colourful and fun.
MADE IN ENGLAND (stamped on the back)
13cm tall and 9cm wide, will look equally impressive on top of your teacup or hanging in its own special place in your kitchen.
I have several blue and 1 white and a couple with little scuffs - the last picture shows one of them.
