Twist N' Lock™ Technology.
Unique interlocking jars with individual lids make it possible to carry supplements, snacks and more–with or without the bottle. Take it or leave it with just a quick quarter turn.
Ditch The Pill Minder.
A covert pill tray locks into any jar lid, allowing you to carry pills and powders in the same container.

I’ve been dealing with issues with the Blender Bottles since receiving them. They would not let me get a refund which I think is not right. I will not be buying a singlet shaker bottle from BlenderBottle again.
