When? Group buy is open now until October 4th 2020. Ships from GMK 32 Weeks after GB closes, so around end of May. Add a few weeks for delays and inter-continental airfreight & importing for most vendors.
Collabs? None. I opted not to create a RAMA cap, at least not for this round. Matching both ABS plastic and anodized aluminium independent from each other based on a RAL scares me too much. Instead I hope to make one in a possible future round where I have the ABS on hand which can be used by the RAMA cap manufacturer to match against, giving us a better match.
