Thank you for viewing. This is an endpin for a double bass. It was originally attached to an Oriente mini double bass. I haven't used it in a while and decided to sell it since I no longer need it. The length is 41cm, and the diameter is 9.5mm. The rubber tip has some fine cracks, but it is still firmly attached and should not cause any problems during performance. Please check the photos carefully and consider that this is a used item before purchasing.
