meagain If you were shipping from China, you would merely wrap it in bubble wrap and affix the label.
My brother got 2 shafts like that from over there, and I got a driver packaged like that. 🤣
Seriously though, I would put it in a decent sized box(6x6x6), it's not going to weigh over 1# anyway, and that will be the minimum you'll spend. With a very small box, the chance to 'get lost' increases.
