Overview
A 12 oz stainless steel water bottle for kids in the Bluey character design, with a push button straw lid and vacuum insulation rated to keep drinks cold for up to 12 hours.
The bottle is built around a kid friendly opening mechanism, a single push button rather than a twist cap, paired with an integrated carry handle for smaller hands. It is meant for cold drinks only; the listing does not rate it for hot liquids, which sets it apart from Thermos food jars.
- 12 oz capacity
- Stainless steel, BPA free
- Push button pop up straw lid
- Bluey character design
Who it's for
Suits a young child's school or activity bottle where a licensed character design and an easy one button lid matter more than large capacity. Not the choice for anyone wanting to carry hot drinks or a bigger bottle for an older child or adult.
Pros and cons
- 12 hour cold retention from vacuum insulated steel
- Push button lid and carry handle suited to small hands
- Removable straw for easier cleaning
- BPA free construction
- Not rated for hot liquids
- 12 oz capacity is small for older kids
Performance notes
Vacuum insulation between the stainless steel walls carries the 12 hour cold claim, and the pop up straw is removable so it can be cleaned instead of trapping residue the way a fixed straw would. Dishwasher use is allowed, though the brand recommends hand washing for longer life.
