Used these on a recent trip overseas. We were surprised what a difference they made! We had to pack for 10 days, which is a challenge for me because I over pack when we stay even for single night. Not only did these help with fitting more into a smaller space, they helped keep things organized and neat, as well. They are also handy for packing a change of clothes and a few toiletries in a carry on. The cubes are very sturdy and we're sure they will last a long time. They come in lots of fun colors (we got gray and red - 2 sets each). These are a great value for the price. Highly, highly recommend.
