I've been using these intensively for heat therapy however one is now coming apart. The outer cover has come open at sealed seam revealing a very thin inner bag holding the "gel" so suspicious of using it more as it may split at any time. Also if I leave them in the freezer to have a cold one ready they do not remain flexible. It takes several minutes for them to become bendable.
This is a great size, holds ipad easily, as well as water bottle and usual stuff. Great as day bag for work. Strap is long enough for easy cross body use. I got black heather colour which is lovely as it has the fleck of white to lift the black.
I got this on a deal and am pleased didn't pay full price because I still can't decide if gemstones are real as they are not cool to touch. They feel like plastic being warm to touch so am not impressed. Length is quite short, my wrists are different sizes and it does fit one but not the other. Pearls and silver seem real.
