Review: A very comprehensive kit, with plenty of each size. Bought to have a stock of washers for my side gig of working on vehicles rather than having to go to the parts store and pay way more for just 1 at a time. The value should pay off in the long run for sure. These seem to be of good quality, and same dimensions as OEM washers of the same type.

Nice and cheap. Don't have to spend $7 for two washers at the auto-parts store when this will last you years at less than twice the price on just 2 washers.
