About Us
One More Diecast was born from a very specific kind of denial — the kind where you've already got three unopened boxes on the kitchen counter, a shelf that's "just temporarily" overflowing, and a browser tab open to something you absolutely do not need.
We make t-shirts for diecast collectors. Not because you need more stuff — you definitely don't — but because at some point you have to wear something, and it might as well say the quiet part loud.
Our designs are for the collector who reorganizes their shelf and calls it a productive Saturday. For the one who knows the difference between a 1:18 and a 1:64 and has opinions about it. For anyone who's ever told themselves "just one more" with complete sincerity and zero intention of stopping.
