A great product
I bought a mini roll to exercise my hand which had temporary nerve damage causing an inability to open my hand. The mini roll was not only a good exercise tool but also made my hand so much more comfortable at nights when I could wrap my fingers around it and sleep without the feeling of my hand being totally clawed up.
I now use the mini roll when I travel as a sort of mini back support, now and then a neck support and also as a foot exercise tool. It is small enough to fit into my hand luggage. It is a great product.
