Here’s a fantastic metal storage box. Actually they come in two sizes: square 14x14x7cm or rectangular 28x14x7cm and made from galvanised metal.
The square one is great as an index card box and for general office (or home) organisation.
The longer one is great for making sections in a drawer. But plants look great in it, change, teabags, jewellery, pencils, wooden spoons in a drawer that need controlling, nuts and bolts or first aid (in our house some not very sticky band aids, old dettol and some out of date painkillers). Make a great stack in pairs (see pic) and also look very efficient when used with the stick on label holders (see odds and sods section).
