NEW STRAW LIDS: We have updated our straw lid so now it can also be used to drink from with the sipping spout; A great way for little ones to start to learn how to drink from a cup VERSATILE: Great for toddlers (less spills) and kids drinks, or use for food storage with the leak proof and airtight lids included; Each jar also has measurement markings for exact portion control; All items are dishwasher, freezer and microwave safe (except lids in the microwave) SLEEVES: Our silicone sleeves bring fun to daily drinks; Not only bright and colorful they are cute with a few surprises from some of Elk’s friends hiding amongst the leaves; The sleeve also provides protection from bumps and drops as well as greater grip for those little hands STRAW STOPPERS: Our toddler cups have straws with stoppers; No more mess with toddlers pulling out their straws; Our straws are also a little wider for those thicker smoothie drinks
