MyMix2go was designed by someone just like you. I always had a hard time taking my supplemental powders with me on the go and then getting the powder into disposable water bottles. MyMix2go is the answer. I use it as a mom for formula though. It’s perfect for keeping formula handy when you are out on the go. A great gift idea for baby. YOUR Mix. How YOU want it, when YOU want it, where YOU want it. Dishwasher safe, BPA free and safe to write on with washable markers to further customize your container. Fun for everyone!
