  • Spinning reel repair....
    Won't being doing the reel repair until Spring, so will need to wait to comment on the spool washers and other items I received. However, the order was handled very well and was extremely happy that your company could supply me with the parts I needed since this an older fishing reel.

    Only one in the package
    Despite being clearly marked as a three pack, both on the site and on the sealed bag I received, it only included one washer. I attempted twice to contact ereplacementparts about getting the additional washers, but never received a response.
