PopYum 9oz Insulated Stainless Steel Kids Cups 2-Pack - Leakproof

In this review the PopYum 9oz insulated stainless steel kids cups come across as a thoughtfully engineered everyday cup set for toddlers and young children. The bottom line is simple: parents who want a compact, durable sippy cup that keeps drinks at temperature and resists spills will appreciate these two-pack cups. The set includes an orange and a sky blue 9oz cup with matching silicone straws and a Twist-Lock lid, and the review focuses on real-world use, cleaning convenience, and how the vacuum insulation and venting affect drinking.

Key Features

• Vacuum insulated seal: Keeps liquids hot or cold for hours without sweating or leaving surface marks, which means less mess on tables and backpacks.
• Unique venting: Small vents let air into the cup as a child drinks, making straw and spout flow smoother and reducing gulping or splashing.
• Triple-wall construction: Encapsulates the vacuum solder seal and makes the entire cup and straw dishwasher safe while protecting the finish from chips.
• Twist-Lock lid: Locks the lid so it will not pop off when dropped and the Flip-N-Lock closure stays out of the way while drinking.
• Straw stopper and stackable design: The silicone straw stopper keeps the straw from being pulled out and the cups stack neatly with or without lids for easy storage.

Who It's For

These cups are aimed at parents and caregivers of toddlers and preschoolers who need a compact 9oz (260ml) cup for daycare, travel, or everyday use. The small size and lightweight stainless steel work well for little hands, and the sealed lid plus straw stopper suit kids who pull or tug at straws.

Families who prioritize dishwasher-safe convenience and temperature retention will find value here. Those who need very large capacity cups, adult tumblers, or a completely spillproof rigid sippy without any straw may want to consider other options.

Pros & Cons

Pros

• Excellent temperature control that keeps drinks cold or hot for hours thanks to the vacuum insulated seal.
• Thoughtful lid engineering with a Twist-Lock and Flip-N-Lock closure reduces spills in normal use.
• Dishwasher-safe triple-wall construction saves time on cleaning and protects the vacuum seal.
• Compact 9oz size and stackable design are convenient for storage and small hands.

Cons

• The 9oz capacity may be too small for older children or long outings when a larger volume is needed.
• While the lid reduces leaks, very rough handling or full submersion could still allow liquid to escape if the lid is not fully secured.

Specifications
