Pelican Cases, Storm iM2100 model.
They have plenty of uses, I?ve seen them used for tools on the worksite, customised for delicate models like Warhammer pieces, lens boxes for cameras, battery storage, high density foam is cheap and you can cut out and countersink your valuables like I?ve done as seen in the first picture. You can also make custom dividers by using corflute thin foam, glued to the side walls then insert the dividers to make custom compartments.
I use mine for my Canon 5D Mark II Camera, Canon Lenses, Field Monitor, GoPro and Accessories and also Hard Drives. Great for electronics, cameras, hard drives, taking them out on the boat for valuables, and many other uses.
These cases are waterproof and buoyant, providing peace of mind when on a boat or out in the weather, I've taken mine to the beach and out on a fishing charter and it's been great. Two hasps are compatible with padlocks so you can lock the lid to the base, while the two press-and-pull latches ensure a tight closure that's easy to access when you need it. They're made from HPX resin which is incredibly durable and lightweight, while a double-layered handle boasts a soft grip for simple carrying. Long-lasting, heavy-duty hinges are flush with the case so they don't snag. Vortex valve allows moisture out, while maintaining waterproof integrity
I only have four cases available for sale at the moment:
$50 per case, if you buy more than three cases, I can sell them for $40 per case. Read more about the cases at this link, they usually start from about $140 without foam for a new case. I have some foam inside these cases, but they?re customised for hard drives, either keep that foam or customised it as you like.
Internal Dimensions are 33 x 23.4 x 15.2cm.
