The Y & R Travel Bottles Set will be very useful for airplane travel where a passenger can only bring 3 fluid ounces of liquids such as shampoo, conditioner, sunblock, etc and are refillable.. They are also useful as a compact way to pack for any travel. There are 6 bottles in a ziplock plastic bag and 3 toothbrush holders to keep toothbrushes from dust and bacteria. They are made of 100% Bpa Free silicone. The bottles are soft and squeezable and are different colors so I can know what liquid is in each bottle. It is easy to fill the bottles as they have a wide mouth. These bottles hold to the TSA standards for travel. There is a 12 month warranty with a 30 day money back guarantee. #RankBoosterReview ii, #Sponsored iii, Y & R Travel Bottles Set, https://www.amazon.com/gp/product/B07G5SFVFD/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
