Have to admit, I kind of forgot about this for a while and as someone else suggested, I reached out to whalebacker directly at the end of October 2025. No reaction initially though. But then in mid-December (~1.5 months later) they replied that they could locate my order and get it moving. Two weeks later I have received the shipment including the limited edition slipcase. The only thing missing was the deskmat, but I didn't really care about that one anyway. Thus, if you haven't received yours yet either - reach out to whalebacker.
