Travel-sized everything: is a new website featuring the best of what comes in a TSA-approved size.

The site is a collaboration between two travelers with 11 years of experience in the beauty industry, Kate Duff and Alexi Mintz. They used to travel together, and Kate would check a bag with all her beauty products, whereas Alexi would carry her bags on — and then have to borrow Kate’s stuff. This wasn’t an ideal situation, and the two spent hours scouring beauty websites looking for 3oz versions of their favorite products. They didn’t exist.

And so, was born, with a brand list including Air Repair, Anthony for Men, The Art of Shaving, Avalon Organics, Go Smile, and Yes to Carrots. The products range from shampoos and moisturizers to teeth whiteners and facial serums for men and women.

As a frequent traveler myself, I’m delighted to see all this great stuff in one place — I frequently find myself relying on the hotel shampoo and conditioner, even their lotion. Some hotels in Europe don’t even offer conditioner. What is up with that?

The 3floz ladies add that these products can also go in your purse, your locker at the gym or school, your work bag and your car (I would add to that your boyfriend’s/girlfriend’s house). Tiny bottles of your favorite beauty and grooming necessities are helpful. Good thinking, Kate and Alexi.

If you shop at 3floz today or tomorrow (February 9 & 10) and use the code STYLEHOUSE, you’ll get 10 percent off your first purchase. Go there.

With a little luck, may help you avoid the following horror stories from the airport checkpoint…
