Long-tube bass clarinet with lowest note C, Cello&Coo LOW-C, with bonus item

I used to be in an orchestra, but I'm moving and would like to pass on my cherished bass clarinet. This is a bass clarinet with a lowest note of C, made of resin (hard rubber). It has a D change register. The detachable neck allows for fine-tuning! Compared to instruments where the register is changed with a thumb button, I believe this one offers a better tone and makes certain ranges easier to play. I had all the pads and corks replaced, and all parts adjusted at a musical instrument shop so it's ready to be played. I'll also include grease, a cloth, a neck strap, and a few unused reeds. I hope someone can use it. You can start playing it right away after purchasing! Instruments are becoming more expensive, but I want to offer this at a reasonable price. I would be very happy if you would consider purchasing it! Thank you.
