CALM 粉末無味隨身包，30 入

I travel a lot for work, so having these single-serving sticks in my bag is a lifesaver. The powder dissolves fine in a plain bottle of water without leaving that gritty residue I've had with others.

The unflavored packs dissolve cleanly in water without that chalky texture I've dealt with before, so I can actually sip it during work without a fuss. Thirty sticks means a full month of easy dosing that I just toss in my bag.

Took these on a camping trip and the single-serving stick packs were perfect for my morning routine — no measuring cups needed, just rip and stir into water. The unflavored taste is genuinely neutral, which I appreciate since I usually mix it into my coffee.
