IC2150 pads are proudly made in the USA! These are premium, white kangaroo leather clarinet pads, with medium, firm felt. This set contains 18 clarinet pads, intended for most Bb clarinets. Many professional musicians prefer leather pads. Please note: These pads require shellac or adhesive pellets for installation, as they are not "self-stick" pads. Please email your clarinet model or pad diameters when you checkout via Amazon message system. If we don't receive your model, we will send the "universal" set which fits approximately 50% of Bb clarinets
