The team behind one of the most iconic supplement shakers of all time Blender Bottle, have followed up on the two variations of their popular accessory. Joining the classic Blender Bottle and it’s colorful counterpart the SportMixer, is a new range of items titled GoStak. The products are basically small containers available in four sizes 40, 60, 100, and 150cc, and nine colors, going from black and white to pink and purple. While the innovation is very simple, it’s highlights are what make it unique. Blender Bottle have designed GoStak to cart around supplements both pill and powder form, fit perfectly inside either of the brand’s shakers combating SmartShake’s attachment technique, and fit together to conveniently carry unmixable foods and items. If you would like to purchase one of the options from Blender Bottle’s new series, they are slowly making their way out to stockists now. Alternatively you can order direct today for between $8.99 to $9.99 depending on the size you are after.
