Pitotubes “It’s Rocket Science for your Packing”. Been testing these new packing tubes out lately, which are perfect for anyone flying, trying to deal with that under 3oz’s/only what you can fit in a 1 quart ziploc rule. Pitotubes was founded by Alisa Caviness-Driscoll, who grew up living and sailing in the Caribbean and worked as a flight attendant to feed her passion for travel. The unique aspect of these bottles is that they are airless (and leakproof!) ~ much like the ones you’ll get in some higher end cosmetic products… as you pump the contents out, the base rises up. My one issue, is that aesthetically, the images looked as if they might be glass/metal, but they are plastic - if there was a more understated model, that might be nice.
