This is the metal spring washer sometimes called an external clicker plate. This fits most Bonika Silk and many other Bonika Shears as well as many other shears. Dimensions 8mm diameter, inside opening 3.2 mm X 4.5 mm
I got the external circular clicker with stabilizing tab on back.
This item needs a round center hole and not an oblong center
The shears that require this option are not all oblong center post
If the center were round it would accommodate all types
NOTE FROM SELLER: Sorry this did not work for you. But we do not guarantee it will fit all shears. We try our best to carry as many parts for shears as we can get a hold off.
A customer of mine needed their shears sharpened and when I received them they were missing a clicker plate. I ordered this and it fit perfectly & the shears work great! Thank you!
