I saw these recommended on a travel blog, and I'm glad I bought them. I used them both in a washing machine and to hand-wash some items on my trip, and in both cases, they were super easy to use and got my clothes clean while taking up a minuscule amount of space in my luggage. I would highly recommend these for extended travel.
As the reviewer down below mentions, it's great to just throw in your purse on the reg for a fragrance re-up throughout the day. As you can see, it's about the size of my thumb and therefore takes up very little room.
