We used to send little chocolate milks with my daughter to school for snack time, but then she developed stomach issues (severe lactose intolerance) and couldn’t drink the nesquiks anymore. Single serving non-dairy chocolate milk is SO expensive and hard to find, so I started looking for a small bottle that I could fill send instead. (We have water bottles, but they hold 18 oz. and are not insulated.)The 9 oz. MollCity bottles have been PERFECT. A dab of chocolate syrup then fill the rest with oatmilk. It’s a perfect serving size for an elementary kid. The bottles don’t leak, they’re sturdy, and they keep the milk cold. They are also super easy to wash with a basic bottle brush. We will make up a couple at a time and just keep them in the fridge so that they’re quick to grab when packing her lunch.I’m buying three more because my other daughter says she wants chocolate milk now as well, but she doesn’t like storebought milks like nesquik. My younger daughter had pink and purple bottles—my older daughter will have blues and greens, so no one will get them mixed up.My ONLY complaint—I’m not a fan of the wristlet part. It gets wet and gross when washing the bottles. I removed the cord and wristlet part (which was extremely difficult), but having the plastic ring still around the bottle with no cord looks weird. I wish there was a way to remove that if you wanted to. It’s not enough to downvote, but I feel like it wasn’t well thought out. My kids put their bottles in the sink with their gross cereal remnants and the dog food bowl that needs washing and the cutting board that I used to prep tomorrow’s dinner—I really don’t want all that nasty stuff touching a fabric wristlet. It’s either going to get hand washed and not properly cleaned, or run through the dishwasher and take two days to dry (mildew city). But I realized it was going to be an issue when I bought it. I already planned to remove the wristlets—I had just hoped that the ring that attached them could come off too. It won’t, at least not in any way that won’t scratch or gouge the powder coating.
