TSA-Approved Liquid Container Reviews
You're probably aware that there are rules about the liquids you can pack in carry-on or checked luggage. If you want a refresher on the rules, check out the TSA-Approved Liquid buying guide.
You can easily get some small travel-size containers and put them in a see-through resealable plastic bag from the grocery. If you want something a bit handier than that, there are lots of TSA-approved container sets you can purchase.
Probably the biggest mistake people make with these containers is just getting them all the same size. Consider that you will need more of some liquids/creams than others. You'll be able to fit more containers in a one-quart bag if they're only as big as they need to be. And, it will be much easier to remove a cream or gel from a small container vs. trying to scrape it off the bottom of a larger container.
This set is interesting. You get 6 containers of different sizes and a clear plastic zippered bag. The upright containers have integrated labels on them, which makes it easy to avoid washing your hair with hand cream. The larger bottles have two small suction cups so that you can hang them on the shower wall during your stay.
Here's another set that has 4 different sized containers and a clear zippered bag.
These bottles also have suction cups so whether you're staying at the Ritz or showering at the state park, you can always find your stuff.
