These empty boxes are suitable for holding our test kits and also fit the small empty vials we sell. Two sizes for 50 and for 100 vials. There are various colours but, because of unreliability of supplies, we do not laways have them all in stock.
The boxes we sell are imported from the USA, so if you live in North America it is much cheaper for you to buy locally. They are bullet boxes made by MTM and are for 44 mag bullets. Find a local dealer.
