Does anyone know where I can find some very very very strong storage boxes?

have also posted this in SN - basically, they need to be chimp proof.

Really Useful are strong, but probably not chimp proof

How about metal trunks? With padlocks?

Really useful do have an extra strong white one... You could contact them and specify what you need it to do, and they can advise?

I asked them a series of questions before about their products, and they were beyond helpful!

really useful boxes are VERY strong.

do they need to be not-get-in-able?
