Seishin = a core concept that reflects both mental discipline and spiritual focus within Japanese martial arts. It has many meanings, like spirit, mind, heart or soul, to name a few.

Our purple and pink "Seishin" steel shaker keeps your drink cold (or warm) for up to 6 hours! With its carefully designed form and choice of materials, it's also easy to clean.

What to expect
No one likes a lukewarm drink. With this double-wall insulated steel shaker made by our friends over at Smartshake, your drink stays cold and nice for up to 6 hours. Inside, you’ll find volume markings in both milliliters and ounces, and a curved bottom that prevents powder from sticking, which makes it easier to clean.

Durability
Rugged 18/8 stainless-steel construction. Ready for war, if need be!

Leakproof and Quiet Mixing
The mixing grid snaps securely into place and is much quieter to use than one of those metal whisker balls. It's also easy to remove and clean properly! And with SmartShake's design, you can also expect a leak-free experience while drinking.
