Stack some snacks! With the BlenderBottle Prostak Expansion Pak, you get 3 containers to pack all the munchies you need to keep you going on your next mountain trek. An extra large 250cc jar fits two handfuls of baby carrots. The 150cc jar is just right for a serving of nuts, and with the 100cc jar, you can fill it with some zesty ranch dip for those carrots. A handy, hidden pill tray fits inside the lid of any of the jars to carry your daily vitamins to make sure you don’t forget to take them on the go. Thanks to their special Twist N’ Lock Technology, all the containers can be connected together, plus you can add the convenient handle to the top for a compact, portable kit, which can be clipped to your backpack with a carabiner for quick access. The jars are top-rack, dishwasher safe and BPA free. Ditch the bags and go with the BlenderBottle Prostak Expansion Pak for all your snack needs!
