I've bought a load of these 0.55 litre boxes from Really Useful Products, as they are perfect for storing my 15mm scale Crossfire 'moderns' platoons. I first spotted one of these pencil-case sized storage boxes in WHSmith, & bought it to try out. It proved to be the perfect size for efficiently storing a platoon plus a few bases of support, so I bought the rest for cheaper online, direct from the manufacturer. They are currently £2.37 each. I may stick some bubble-wrap or foam in the lids to protect the figures more, but I'm really pleased with this storage solution. Previously I had been storing all of my forces haphazardly in plastic chocolate boxes - these take up up less room, you can see the contents without opening, & they are more convenient for transporting.
