Frequently Asked Questions:

Where do you get all this stuff? 

We've been buying and selling unique surplus technology since the late 1990s. Over that time, we've amassed quite an assortment of scientific and industrial materials from the government, research facilities, startups, and business liquidations, to name a few.

And mystery boxes are a great way for us to clean house and provide exceptional deals to you at the same time.

Is it still a mystery box if you're showing me pictures of what's inside? 

Yes! We provide pictures of each Obtainium Mystery Box's contents because we are often unfamiliar with their unique nature and need more knowledge to accurately describe them - hence, the mystery part of the box. Additionally, showing lots of photos means that no-doubt somebody will identify an obscure article, or two, that they didn't know they were looking for.

Does all the stuff in the Obtainium Mystery Box work? 

Well, let's say we haven't taken the time to clean up or test everything inside each mystery box. And to be perfectly honest, that's part of the attractiveness of it all. The less time we spend putting mystery boxes together affords the continuing opportunity to let stuff go at a low price. Hence, everything in an Obtainium Mystery Box is offered AS IS, without exchange or refund.

Obtainium have been a very helpful seller to me.

In recent times I have had a few items go astray enroute to my address in Australia. This seller was most helpful & encouraging, regarding the onward tracking & eventual safe delivery of this item. This item's arrival in good condition was a joy to me as, it was a rare part that fitted my military comms. Well done seller. I would gladly recommend this seller to all potential buyers.
