I have started using all natural toiletries and I unfortunately, they don't typically come in travel size. I purchased these for a business trip to carry my shaving cream, shampoo, conditioner, body wash and hair wax. They worked as expected. They are very compact and fit in the front pocket of my carryon bag. They came with a clear plastic bag to hold everything. Nothing leaked during my trip. I would recommend to anyone that needs to take a trip with limited luggage space and needs to get through TSA checkpoints.I used these on a trip to Spain. I packed it in my carry on and traveled to three cities without any problem at all. No leaks, cracks or anything unpleasant at all. They seal well and got through TSA without incident. It even includes it's own pouch which is TSA approved. The only problem with this was the zip top which busted open but I did overstuff it so that was my own fault. Other than that, great product!These are fine but I would advise you NOT to put thin liquids in the 3 bottles with the pop-up lid. I recently used these on a trip and the spray bottle worked fine for thin liquid - but my facial toner in one of the others leaked everywhere. Lotions, creams, conditioners are fine - but I'd only trust thin liquids in the spray bottle (& even then I'd put all of these in a Ziploc-type bag!). Good luck!I mainly ordered this set, due to the amount of pot containers that it came with. I like that it came with a bottle that had a spray pump. Didn't know i wanted that one... but glad it came with it. Also, the clear case that it comes in, is great when you have to send everything through the x-ray machine, at the airport. Everything can stay contained, without having to transfer all of your 3oz. items, into the airports ziploc bags.Worked well for TSA travelling. I was very happy for the price I paid. They aren't the most sturdy of bottles, but exactly what I needed and wanted for my trip. I don't travel much, so I didn't want to spend a lot of money on something I may not use for a long time. They didn't leak or have any issues.Really useful set. The spray bottle I use for watering air plants. The three tiny containers are great for moisturizer and sunblock on the go. I thought one of them might have leaked just a little (the outside was a bit "greasy" feeling), so I subtracted a star, but if kept in a plastic ziplock bag, it's a minor inconvenience.I purchased this for a recent flight. I had no issues getting this bag and bottles through security. As described, it meets TSA guidelines. The liquid bottles were sufficient for storage. The 'jars' however did not make a good seal and did leak. I ended up getting rid of those and just using the liquid bottles.BOUGHT THESE FOR OUR TRIP TO DALLAS. THEY WERE ABSOLUTELY PERFECT FOR OUR TIME THERE. WE STAYED 5 NIGHTS AND WERE ABLE TO BRING ENOUGH SHAMPOO, CONDITIONER, TOOTHPASTE, FACE WASH, LOTION AND SOME PERFUME IN THESE. HOWEVER, NO ONE EVEN LOOKED TWICE AT OUR LIQUIDS, BUT IT WASN'T WORTH TAKING A CHANGE. THESE ARE PRICED PERFECTLY AND WE WILL BE ABLE TO REUSE THEM. I HIGHLY RECOMMEND USING THE SELLER AND PRODUCT!Small size
