These are 4 leather saxophone pads size 26mm (83 is printed on the back of each pad--a product number?). I inherited them from an instrument repairman when he retired. They are in the small paper bag as I received them and have been carefully stored in a smoke-free, pet-free home for some time. I don't know the brand.
These pads look like they are in Like New condition however I do not know the subtleties of saxophone pads. They have never been used or installed in an instrument. There are no signs of resin on the back. The edges of the pads are clear and clean, no breaks in the leather and the pads are flat. I have a lot of sets of various sizes and it seems a shame to throw them out if they could be of use to another repairman or musician.
