I've got my Sturmey Archer oil. Shipped it through the mail (USPS). The can leaked slightly in shipping (lost maybe 1/2 teaspoonful) but it was in a heat sealed plastic bag so didn't escape beyond. I put a circle of moleskin under the cap for a sealer, and it leaked through. [Take notes, kids. Moleskin is not oilproof. Never know when that information might be useful.]

BTW, the can was labeled "99" in green marker which I believe was the price - 99 cents in ~1974. We used a very professional price-tagging system back then, along with our ding-box (cash-register) which required putting a nail into a slot to make the cash drawer open. And if someone paid more than $50 with a credit card, you had to make a phone call and get an authorization number before accepting it. Ah, the halcyon days of small business.
