17 Oz Shaker Bottle, 2 Twist n' Lock Storage, Plus Pill Organizer, Also Comes With Spring Whisk, BPA-free

Mouth opening does not snap shut.

Awesome. Hold my protein mix and pills in a convenient screw on bottom piece. And it's a great price.

keep in mind how small the cup is without the other pieces, wonderful shaker though, doesn't have the shaker ball, has a weird insert
