I lost my 4mm guitar tremolo, after I moved.

I checked AMAZON but could only find 5mm and 6mm sized ones.

I even reached out to my buddy GOOGLE but had no luck finding a source.

I was wondering if anyone can point me in the right direction.

My guitar was sold by "all in one guitar" but they did not have one in stock.

I use it to rest my strumming hand on it, it works well for me. I do not yet know how to use it properly and it only can be pushed in one direction, inward. But to rest my hand, it works well.

Fingers crossed

Thanks
