JASSC MRC-ZERO Microphone Clean Shower - 10-piece set Brand new, unused. I'm selling these because I have extras. I am not a shop. If you require a receipt or a qualified certificate, please purchase from an authorized shop. This is a personal sale, so I must decline sales to those who are overly sensitive or seek perfection. Also listed elsewhere. Please forgive me if an item sells out due to timing differences. jassc microphone clean shower MRC-ZERO
