Great product!
These are great to keep my makeup brushes in shape after they have dried. I haven't traveled with them yet, but I will when I do to keep everything more compact. Works minimally on really skinny brushes, but still does the job. If you choose to reuse, you must place the product on the same or another brush of greater or equal size. It doesn't shrink back to its original size once manipulated.
