I bought this Custom Fit Espresso Tamper on ETSY. I used it one time and don't like it. Maybe some else will.
The size is approximately 58.4mm.
There is a fine nick on the top, almost not seem. Other then that- brand new.
I paid $35 include the shipping, and I will sell at $24 include shipping to CONUS.
Used espresso or coffee stuff you hope to sell or buy.
