Exact listing where I bought mine. Took 12 days to reach PA form China.
Literally found this website looking for a solution to putting a zero stop shim in my 10x classic mil/mil.
Ended up seeing the dimensions in post #16 of this thread and ordered some nylon washers from China off eBay for $4 per 50.
Size was metric, 12mm ID x 24mm OD x 2mm thick.
I have a 40...
