KeepCup Cold Cup Longplay Double Wall Glass Tumbler - Chalk

Our review of the KeepCup Cold Cup Longplay finds it best suited for at-home cold brews, iced matcha and anyone who values a clear, taste-neutral drinking vessel. The single biggest reason to buy is the tempered glass construction that preserves flavor while keeping condensation off hands thanks to a removable sleeve. It is quietly designed, holds a reasonable 16oz, and includes a spillproof lid and 12mm boba straw for easy sipping and swizzling.

Key Features

• Tempered glass cup: Premium glass provides a clean, non-reactive surface that helps preserve the true taste of cold coffee and tea.
• Removable clear sleeve: The plastic sleeve reduces condensation on the outside of the cup and protects the glass during everyday use.
• Spillproof straw lid: A press-fit lid with a spillproof valve keeps splashes contained while allowing easy straw access for sipping on the move.
• 12mm clear boba straw: The larger diameter straw is great for thicker iced drinks and for stirring without removing the lid.
• Heat resistant silicone band: A colour pop silicone band improves grip and adds a visual accent while staying cool to the touch.
• Recycled content: The cup and lid include recycled materials, reducing virgin plastic use without compromising function.

Who It's For

The KeepCup Longplay is a strong choice for home coffee brewers, matcha enthusiasts and anyone who prefers drinking from glass rather than plastic or metal. Its double wall glass design and removable sleeve make it especially convenient for drinks that are iced or that tend to condense on the exterior.

Shoppers who need oversized servings or a fully leakproof travel mug for long commutes may want to look elsewhere, since some users note the capacity can feel smaller than expected and the lid is designed more for spill resistance than complete leakproof performance.

Specifications

Our Verdict

The KeepCup Longplay Cold Cup is a well-made glass tumbler for people who drink cold coffee, iced tea or matcha at home and want a clean flavour profile and minimal condensation. Its tempered glass, removable sleeve and wide straw make it a practical, attractive option; buyers who need larger capacity or a truly leakproof travel bottle should consider other styles.

Frequently Asked Questions

Is the cup dishwasher safe?
KeepCup tempered glass and silicone band are generally dishwasher safe on top rack, but hand washing will extend the life of the silicone and lid components.

Does the lid prevent leaks?
The press-fit lid has a spillproof valve that reduces splashes, but it is not designed for prolonged upside-down leakproof transport.

Can I use hot drinks in this cup?
The Longplay is designed for cold drinks; the removable sleeve and double wall help with cold insulation and condensation rather than hot beverage heat protection.
