This leak proof travel bottle set is very handy for travleing. I can take my shampoo and condition, body wash and lotion and some face cream and toothbrushes in one handy cary bag. It all zips together and can fit easily into a carry on bag. It is made of durable silicone material that will last a long time. It is TSA approved so ther ewill not be delays and you won't have to throw them away because they are not approved to carry on or pack. They have wide mouths to fill and are easy to squeeze when you need the stuff in them. The tops snap shut and are air-tight. All in all this is a great set to have for traveling!
