Well this was unexpected. I ordered some small batteries from China several weeks ago. The other day, a package arrived.
I opened the padded envelope to find two cheap plastic cars. "What the hell? I didn't order any plastic cars from China via Swiss Post," I thought. But the address is correct ... the supplier must have messed up my order. (That would be a first - I've had a couple things not show up, but never be flat out wrong.)
"Huh, there's something rattling inside here," was my next thought.
I broke open the cheap, hollow plastic car to discover a battery inside each.
Well, I haven't seen that before.
I suspect shipping in this way is due to recent changes the USA has made to shipping regulations. The USA says lithium-polymer cells can no longer be shipped by air, except as part of a device (i.e. installed as part of something else.) Perhaps this is an effort to obey that regulation in letter, if not in spirit.
