WIX oil analysis shipping?

[00scrub]

Hi I recently got some of the WIX oil analysis kits off Rock Auto. It isn’t clear to me if I’m supposed to just ship them in the black plastic bottles along with the included address label or package them up in my own box/envelope and attach my own shipping label.
What have others done?
Thanks

Put them in the smallest box you have. The post office gives people a hard time if you ship it in just the black bottle

they should have a mailing envelope (plastic pouchy type)
or use a small box

Thanks guys. I’ve got a bunch of boxes and envelopes I can use.

Is there a difference between the labs? I think the Portland one is closest to me.

No difference between the labs, just use the closest
