JAXX Glass protein shaker was designed as a counterpoint to the common place plastic shaker bottles. The glass core is easy to clean and keep clean, and being super clear you can make sure your powder is fully mixed. 

Inspiration for the plastic and silicone protective sleeve came from high end cell phone cases, and can endure 6 foot drops onto concrete. 

The enclosed JAXX mixers were modified to be smaller and leave the glass surface unmarked and undamaged.
