We have complete sets of our first 18 metals, all with matching serial numbers available for pre-order now. They will be available in time for Christmas delivery. We just have to finish processing our In, Lu, and Sb ingots to complete the sets. This is a unique collection of some of the rarest metals in the universe. Only 7 such sets exist, and only 4 are left as of today. This would be a great gift for that gold bug or collector of rare and beautiful things you know that seems to have everything. There is no chance they have this! We guarantee it and if we are wrong and they don't absolutely love it you have 30 days after Christmas to return it. Own what's rare.
