Ont eh Hobby Machinist (H-M) forum they have a thing where a flat rate box is mailed around to forum members who sign up to receive it. People agree to take something and replace it with something else.
I've pasted some of the pertinent info from H-M:
"We start off with a medium sized flat rate box from the USPS. It has a stainless steel interior box which is filled with various odds and ends, doo-dads and goo-gahs, not to mention thing-a-ma-jigs and whatchamacallits (highly technical terms for various machine shop related items ). The box gets sent from one participant to the next and the next, with each participant removing items of interest from the box when it arrives, then putting other items in their place before sending it to the next individual. This box will circulate down the list until late summer, early fall at which time it will be returned to the admin in charge. It is a lot of fun with some nice surprises along the way!"
Here's a link to the start of the 2023 thread. I think non-H-M members should be able to read it. If not, let me know and I'll see what I can do about reproducing the info here.
