You are looking at one set of 6 nylon replacement washers for older Warwick tuners which use one metal washer and one plastic washer (please see 2^nd picture). A set of 6 washers is adequate for changing all the worn-out plastic washers on your beloved 4-, 5- or even 6- string Warwick bass.

3^rd and 4^th pictures show how these custom-made nylon replacement washers fit perfectly on a 2012 German Warwick thumb bass. The general washers sold in hardware stores just won’t fit.  

Made from nylon, these closed-ring washers are more stable and durable than the original open-ring, plastic washers.
