10oz Stainless Steel Kids Mason Cups 4-Pack - Spill Resistant

In this review of the Elk and Friends 10oz stainless steel mason cups, the bottom line is simple: these jars are built for everyday kid use and make drinks and snacks portable without a lot of fuss. The 10oz size fits small hands while holding enough for smoothies, milk or juice, and the set balances durability with easy cleaning. Parents will appreciate the thoughtful combo of a straw lid and a leak proof storage lid, plus silicone sleeves that reduce dings - overall a practical, low-maintenance cup set for active families.

Key Features

• Perfect size: The 10oz capacity is large enough for a toddler's smoothie or juice but small enough for easy handling and daycare use.
• Durable materials: Stainless steel body and food grade silicone sleeves provide a non-porous, long lasting surface that stands up to daily bumps.
• Dual lids: The set includes a straw lid for independent sipping and a leak proof storage lid for snacks or leftovers.
• Straw design: Each silicone straw has a built-in stopper to prevent it from disappearing and is wide enough for thicker drinks like smoothies.
• Dishwasher safe: The cups, sleeves and lids are all dishwasher safe so cleanup is quick and the sleeve does not need to be removed.
• Lightweight and portable: These jars are easy for little hands to carry around on errands, playgrounds or at home.

Who It's For

These mason cups are ideal for parents of toddlers and preschoolers who want a sturdy, mostly non-plastic drinking option that is easy to wash and simple to use at daycare, travel or home. Families who give smoothies, milk or juice to young children will like the wide straw and manageable 10oz capacity.

Those who need fully spill-proof drinkware for car seats or for toddlers who constantly tip cups should look elsewhere; because the straw lid has no valve, liquid can leak if turned fully upside down. Also, very small infants who require sippy nipple styles may prefer a dedicated sippy cup instead.

Pros & Cons

Pros

• Well made with a cute, kid-friendly design and resilient silicone sleeves that protect against drops.
• Easy to clean and dishwasher safe without removing the sleeve, which saves time for busy parents.
• Two lid types add versatility for independent sipping or sealed storage of snacks and leftovers.

Cons

• The straw lid is not completely spill-proof if tipped upside down since there is no valve, so leaks are possible during rough play.
• Some customers have mixed feelings about the straws, with a few preferring alternative straw materials or thicknesses.
