4ml Screw top container (opaque) **NEW**
A high quality opaque nano container with a screw off top and a flat bottom (will stand vertically on its own). Ideal for those sneaky hides. Size 5.8cm x 1.5cm.
A Neodymium magnet can be used on the outside of this container to secure the item to metal railings, benches, etc. and is avaliable as an optional extra.
Please note: Unlike our 2ml screw top containers this item does not have a rubber seal in the lid but the screw down lid is still adequate enough to keep out inclement weather.
