Oh, damn! I’m so jealous right now!! I guess I can’t pursued you to sell it to me? 
EDIT: Funny how it’s still a 3D stamp. And it’s not as thin as the actual Thin stamps from the Base Holos or other sets, but it’s a border-line Thin stamp regardless, compared to the regular wider Thick stamp.
PS: @hoax The ones you’ve shown are Grey stamps, this above is a Thin stamp. See this article I wrote about 1st edition stamps to read why.
