Looks like a little metal key-chain type deal.

Don't trust it. It's Chinese. Looks cool. I wonder if it'll get a US release?

I think i started a tread here in june... found these at my 7-11, except that they were in bind boxes, 17 in total to collect. Yeah they are stamps, 8 of regular colours, 8 of gold (same mould) and a last "super rare" prime with swords.

They cost $3 per piece as of SGD and i got a regular SS and gold megs. Meh... nothing that special ... but they make good paperweights.
