Elk and Friends Kids & Toddler Drinking Cups - 12 oz Glass Mason Jar

In this review of the Elk and Friends Kids & Toddler Drinking Cups the bottom line is simple: these are thoughtfully designed 12 oz glass mason jars made for families who want a safer alternative to plastic without sacrificing convenience. The jars are perfectly sized for little hands and big thirsts, and the combination of a protective silicone sleeve, wide straw with stopper, and two lid options makes them versatile for smoothies, water, milk and quick snacks. For parents who value clean materials and easy care, this product stands out as a practical everyday cup for toddlers and young children.

Key Features

• Original 12 oz glass jar: The 12 oz size fits small hands while holding enough liquid for a meal or snack, making it useful across the day.
• Silicone sleeve protection: The sleeve cushions the glass against bumps and drops so active kids can carry jars during play or travel with reduced worry.
• Two lid options: A spout style lid with silicone straw introduces independent sipping, while a leak proof storage lid doubles as a cover for snacks or leftovers.
• Wide straw with stopper: The straw is wide enough for smoothies and has a built-in stopper to prevent it from falling out, helping keep parts together during use.
• Safe, non-porous materials: Made from glass, food grade silicone and BPA-free plastic, the jars are microwave and dishwasher safe for easy cleaning and long-term use.
• Environmentally mindful design: The jars are a reusable alternative to single-use cups and reflect the brand focus on natural, durable materials since 2015.

Who It's For

These jars are best suited to parents and caregivers who want a reusable, non-plastic drinking cup for toddlers and preschoolers that is easy to clean, attractive, and durable enough for everyday home and outdoor use. The 12 oz capacity and wide straw make it a good match for smoothies, milk, juice and water for children learning to drink independently.

Families who need fully spill-proof cups for car seats or overnight travel should look elsewhere, since the design favors straw width and easy flow over valve-style leak sealing. Also, households that require unbreakable plastic only may prefer non-glass options despite the protective sleeve.

Pros & Cons
