I've bought a couple of these now and use them to hang on the sides of my bookcases. I've got a few extra magnets for not a lot of money and have over a dozen photos on each. They're a talking point and its easy to change photos for newer ones instead of faffing around with photo frames.
Knew this was small but I got it here for £12 with the express purpose of using it as 2 separate lens cases. Fits the bill perfectly for that, couldn't get this amount of protection for 2 lenses for a much better price.
