I have recently bought quite a variety of the storage boxes sold by the Really Useful company and they have all proved to be very sturdy and useful. I am using this particular box for items I have that link with my family tree research - such as medals, brooches, badges and other paraphernalia that is hard to store safely. Other boxes are being used for sewing bits, envelopes and miscellaneous stationery and CDs. They are more expensive than many found in the shops but they do not warp and the lids fit very securely and can be attached and removed with ease - unlike some other boxes I have bought. You get what you pay for.
