Overview
A 19-ounce insulated stainless steel water bottle for kids, built with a straw lid, spout cover lock, and carrying handle, decorated with Huntrix characters Rumi, Mira, and Zoey from KPop Demon Hunters.
The listing sits under a thermos category, but the specs and design describe a kids' straw water bottle rather than a food thermos: a 19-ounce vacuum-insulated bottle with a straw and flip-lock spout cover, sized to fit a cupholder at 4.30 by 3.01 inches wide. Double-wall vacuum insulation keeps cold drinks cold and stops the outside from sweating onto backpacks or car seats. It is recommended for kids age 3 and up, with a lid that comes apart for cleaning.
- 19 ounce capacity
- Vacuum insulated double wall
- Flip-lock spout cover
- Huntrix character design
Who it's for
Parents buying a durable, licensed-character water bottle for school or outings with a child old enough for a straw bottle. It is not sized as a hot-beverage thermos or for capacities beyond 19 ounces.
Strengths and trade-offs
Drawn from this product's published specifications.
- Vacuum insulated stainless steel keeps drinks cold
- Locking spout cover reduces leaks in bags
- Top rack dishwasher safe
- Fits standard cupholders
- Sized for kids age 3 and up, not adult-size servings
- Not intended for hot beverages
Performance notes
Vacuum insulation between double stainless steel walls keeps cold drinks cold for hours and prevents the exterior condensation that leaves rings on tables or soaks through backpacks. The flip-lock spout cover is meant to stop leaks in a bag when the bottle is not in use, and the straw and spout come apart for dishwasher cleaning on the top rack.
