PROSTAK
Blenderbot Prostack products connect the powder, medicine, and storage boxes used for storing capsules to help you get powder and medicine capsules anytime, anywhere. Two storage boxes are provided for each product in the lower section of the Prostack. Prostack is 22 ounces (650ml) in one size.
GOSTAK
Blenderbottle Gourstack products can be consumed with supplements, powder, snacks, and vegetables needed for exercise or outdoor activities, and are also widely used for side dishes and condiments in kitchens. When using with the Blender Bottle Sports Mixer, you can put the old bag in the sports mixer to minimize volume and ease the use of the bag.
EXPANSION PAK
The Blenderbottle Expansion Pack, like GoSteak, is an easy way to carry with you any mixture, snacks, or vitamins you need for exercise or outdoor activities. If you think you have insufficient storage space, you can detach it in the lower part of your Prostack and use it in an expansion pack.
