Here is a perfect condition GB-187, the infamous matrix rip-off that everyone is trying to get. IMO it functions JUST like a real matrix and for being a china piece it is put together quite nicely. US ONLY. Unless you are a known member here and we work out a trade you will need to send the item first and then I will send mine. Mainly looking for trades on this one but feel free to hit me up with any offers. Looking for a mflb finishing grinder, mflb wooden mouthpieces, pinnacle WT, or a eds tnt wooden solo stem.
