Info: A Ball Set in a Base to Roll for Stress Relief
There are two types on offer.
For the Standard version, each one has a 2.75"/7cm diameter base which is black in colour with a Khaki green coloured ring around it, and they have a 2"/5cm diameter marble-textured plastic ball, whose colours vary - coming in Blue, Green or White.
For the Harmony ICE Roller, the base is different, slightly smaller (2.55"/6.5cm), and may come in blue, black, or grey. They all come with a high quality, food grade stainless steel (304) ball, which can be chilled by placing it in the freezer or somewhere cold for at least two hours before needed, so you can combine treatment modalities, for both deep, targeted pressure and therapeutic cold application.
