eBay

I've collected many different used Allen Key's over the years and mostly they are the cheaper ones, probably not hardened. Some are good quality (mainly the bigger sizes)

I got these metric and imperial ones: (Selling in pairs). If you order one you get 2 Allen keys of the same nomination. Some look better than others!

They are used, not perfect. If the ends are not perfect you can file them flat.

Sent out in standard envelopes. Postage is $1.10 - $2.20 (included in the price). No tracking. If you want tracking, add $8.00 for a small satchel.

These are the only nominations I got extra pairs of, for sale:
