Query: Great Product! A must have

These travel cubes are genius! Anything with Rick Steve's name on it is good quality and a must have. These are super light weight and practically collapse down to nothing. They also fit great in my Rick Steve's convertible carry-on bag that I own. There's lots of packing cubes on the market but you can never go wrong with Rick Steve's.
