The "Echo" is a cello endpin stopper handcrafted from maple, the same material used for the back, sides, and neck of the instrument. Its strong non-slip effect works on any floor surface, securely holding the cello's endpin at the optimal angle and returning a rich resonance to the instrument. Retail price: 15,800 yen Used a few times for practice at home. There is a hole where the endpin was inserted, but otherwise, it is in relatively good condition.
