Magnet and Steel

[Tony of TTT]

I supply magnetic sheets and Ferrosheet (that magnets 'stick' to).

http://www.tinytintroops.co.uk/Bases/Fl ... sheets.htm

The magnetic sheet is 0.8mm, not the strongest you can get but adequate for up to 28mm figures. Ferrosheet is a fairly new product for me and is much better than most of the thinner versions sold by others (0.8mm compared to the norm of 0.5mm).
I do three sizes, including both A4 and RUB (4lt & 9lt boxes) and it sticks really well to the plastic used (which not all versions do).

Also happy to help & advise on choices and options - or any queries about magnetic storage.
