ShakeSphere Tumbler View w/ Clear Window-727. 5ml. Here's how a ShakeSphere bottle works. Instead of using mixing accessories like a wire ball or mesh grid, our bottles use the centrifugal force generated by a round, no-corners design to break down powder supplements in a mere five seconds of shaking. Shake for another five seconds and you can even enjoy soft fruit in your shake for the ultimate post-workout boost. , , You may think having no mixing accessories means a lot of wasted shake. You'd be wrong. Because there are no corners, nothing gets left in the bottle when you've finished with it. This not only means you spend less time cleaning it, but also saves you money as you need less powder in the long-run. No waste also prevents the build-up of the foul smells which develop when undissolved powder lingers in the corners of your typical shaker bottle. It's no wonder ShakeSphere was voted Best Protein Shaker 2019 by Men's Health and have already received 9 awards this year recognising the Tumbler as the best shaker on the market right now. , , The unique capsule design of the bottles are patented, meaning there won't be anything else like it on the market and you'll stand out from the crowd. The capsule shape is moulded using a high-quality plastic which is free from BPA, protecting you from harmful diseases and making you feel good. At the top of the capsule, you'll find a sturdy slide cap which ensures your bottle will never leak wherever you take it. This product comes in a Rose Gold, Matte White, Matte Black or Gun Metal finish with a clear window. Remember that it's not dishwasher-safe but can be handwashed in seconds using just a little bit of water.
