Not the exact size of a standard M1 blank
These are slightly shorter than other M1 blanks, but work fine.

Good quality
Good quality at a great price. I buy keys in bulk from Amazon for my side hustle and for basic keys these can't be beat. I can't tell the difference between these and the ones I get from a regular locksmith supplier.

These keys are not to specifications, they are 1-3 thousand of an inch off. Which makes them too large to use, I had to file the bottom of the blade to make them fit.
