I ran by a CVS today to pick up some shaving gel, as the stuff I had at home was too large to pass the Kip's Zip muster.

I noticed one brand--Gilette, I believe--that came in a fairly small can. It was labeled "NET WEIGHT: 100mL / 3.4 oz."

I almost laughed out loud in the store. First, this is the WORST example I've ever seen of confusing weight and volumetric measurements; usually, the confusion is on the oz / fl oz end of things, not the mL end! Second, it's uber-convenient, it would seem, that the "weights" match the current TSA guidelines.

I also noticed that my normal travel shave gel, in the exact same size can I already have but which says "Net weight: 5.6 oz" or something like that (which is why I left it at home!) now says, "Net weight: 3.4 oz"

Seems like people are manufacturers are doing all they can to capitalize on Kip's Folly.
