This is a model made by EIGEN HEART, a musical instrument store in Japan (Yokohama). The instrument itself is the same as a Besson, and it's a euphonium made in China via OEM production. The model number is EHEP-400S. The quality is quite good. The old image of Chinese-made instruments is blown away. It plays well and is well-made. It's a full-spec model with compensating system, trigger, and two water keys. A Bach 5G mouthpiece is included. I opened the case to store it, but I never used it because I was using another mouthpiece I had. Although there are some minor scratches and signs of use, it's clean as shown in the photos because I've only played it 4-5 times. However, it is still used, so please understand that we cannot accept claims or returns. The pistons and tuning slides are in perfect condition. I don't have a large cardboard box, so I will ship it in the case.
