This is a set of two pop blockers. The manufacturer is unknown, but they are well-made. They were only used for a short period of time, so they are in relatively clean condition, but please forgive any minor scratches. Maximum total length: approximately 44cm 360-degree angle adjustment is possible. They will be packed in a 60-size box, so they will be shipped in a bent state.
