Agreed, I just looked at the size difference at the start of the thread. Now I have a question. Is there only two sizes? Or is there discrepancies between different versions? aka slightly smaller/ slightly larger. My R1 soft vault is slightly larger than a newer one I bought in the last year, but their size difference is not as apparent as the ones at the start of this thread.The XS is longer and will not fit in the smaller Xmetal softvault.
