Silicone Travel Bottle
Wow. These travel bottles are awesome and I can't believe I haven't seem them before. They have a wide mouth for easy filling, an "o-ring" seal to prevent leaks, and they rest upside down on your counter so that you can use all of the product. They also have a simple rotating icon system that helps you indicate what's in the bottle. They are made from silicone so they are super easy to squeeze, and they're carry-on approved. How wonderful.
