The pocket physio aka ‘the nose’ is made up of hard rubber and is best described as being a nose shape, hence its nickname. They are small and fit in the palm of your hand and again as the name goes they are designed to be carried in a pocket.
I mainly use this item to loosen up my chest, shoulders and neck but there is really no limit to its use (see the free video that you get with every purchase). The reason I really like this product is because it can be taken and used everywhere. The unique shape of this item also allows you the use the different pointy bits to massage and treat any sore tight parts of the body. Have a play and find out what works for you.
