PLASTONE flexible file (FLEXSTONE)

Plastone® flexible, non-conductive files are just the right tool
for burnishing and cleaning corroded, carbonized, cruddy contact
points, especially on pre-1977 manufactured electro-mechanical
machines. Replacement for FLEXSTONE file.

(Don't file switch contact points on post-1977 solid state games;
most of these contact points are gold plated).

These 3/8" x 4-3/4" x .04" thick, non-conductive, inexpensive
files are impervious to oil and water and may be rinsed with soap
or solvents to remove dirt and grease.

180-Fine grit.
