If you have an extensive hygiene routine, you’ll appreciate being able to group all your products by label! And after testing the Capsules for more than a month, I can attest that these little suckers are total pros at storing all my stuff, from pills to oils. Or to be the person that holds up the line at security while the TSA agents discard your oversized liquids. We also liked the stylish, see-through carry bag and the fact that there’s a special place on the caps to stick the included labels so that they adhere properly.

While going through TSA, the airport I was in was oddly (and insanely) strict about liquids that day and gave out 1L bags to everyone. If you’re planning an extreme adventure, technical options like the waterproof flat-pack bottles from Matador may be worth the extra expense.Between you and us, we rarely encounter excellent ones, and even then, they still fall short of what we have at home. Before, I easily filled two dopp kits when packing toiletries for the family (2 adults and two young kids).

I agree with Jafei here that there are travel containers out there that can hold way more and are cheaper. They had to create over 200 designs to reach this sustainability point until they were satisfied and felt they had the perfect design. The texture of the Capsules are are slightly pebbled, which is quite nice, and keeps them from feeling too slippery. The Cadence Capsules may not hold a week’s worth of shampoo, but they make up for it with magnets, a packable shape, and solid build quality.Instead of carrying a large Tatcha jar like this one for my Dewy Skin Cream (that I can’t live without), I put a few scoops of Tatcha in a Capsule that’s a quarter the size of a jar! These are so small, I don’t see how they could be an issue, but I also think they could do half sizes for serums and cleansing waters etc. I've had some of these toiletry bottles for over a year and they've accompanied me on a mix of weeklong vacations in checked luggage and short weekend trips in tightly-packed duffel bags.

For those short trips, though, these are quite convenient to use thanks to their magnetic features and thoughtful design. I need contact solution, toothpaste, Aquaphor, body lotion, shampoo and conditioner, not to mention aloe vera for sunny vacations.I don’t really have a huge pitch as to why you need these in your life, but if you travel consistently or need help making your life feel more put together… These could be your answer. That said, the capsules are leak-proof and watertight, so once the cap’s firmly in place, nothing’s getting in or out. Probably not as light as your average, reusable travel-sized plastic bottles, but they might take up less space at the end of the day since they stick together. I can attest from several successful flights that these are truly leakproof, watertight, airtight, and TSA-approved.
