I got the same email today.
Online Metals has these things called “Protoboxes”. I had no clue about them, but I called there one day a month or so ago asking if they ever had “drops” or “off cuts” that they sell. That’s when the guy on the phone mentioned the Protoboxes.
I bought a Protobox of 1018, 303 SS, brass & aluminum, when I got them, I thought they were great. A lot of variety in the material I received (round stock, bar stock, tubing, square stock, etc). I liked it because I’m kind of new to this machining world & I would have never ordered some of that stuff.
So next time I place an order from OM I will be shoving a Protobox or 2 into the order as well.
