Protect stringing materials from undue wear with Wire Guardians. Reduce abrasion from clasps or other sharp edged components. Use Wire Guardians in the same way you use french wire, the only difference is the Wire Guardian is rigid. For wire diameters up to 0.53mm (.021) made by Beadalon (packaging may vary) These were $15.00 a bag. SUPER SPECIAL PRICE until stocks run out. Why not use these with the new Beadalon silver-rose beading wire.
