The F-32 Shark Mug is a specialized lightweight vessel designed to increase hydration compliance in toddlers through its 3D tactile design. It features an internal 201 stainless steel liner encased in a synthetic resin shark-shaped shell. Because this design uses an air gap rather than a vacuum seal, thermal retention is limited to approximately 2 hours. This makes it most suitable for immediate consumption during a meal rather than for long-term storage of hot or cold drinks.
This mug is extremely lightweight, weighing about 150g, which makes it very easy for small hands to lift and hold. However, the ornamental plastic exterior is more brittle than standard steel bottles and can crack if dropped from high-chair heights onto hard floors. The lid includes a silicone gasket that should be checked for placement to avoid minor leaks. Due to the materials used for the 3D design, this mug should only be hand-washed to prevent the adhesive from failing in high dishwasher heat.
It is important to note that this is intended for upright use; it is not a direct replacement for a fully sealed sippy cup in a bag. The internal 201-grade steel is functional for water or milk, but for very acidic juices over a long period, a higher 304-grade steel found in other models might be more appropriate. It remains a high-engagement tool for getting toddlers excited about drinking water.
- Lightweight 150g build is easy for toddlers to manage.
- 3D shark design helps encourage drinking.
- BPA-free polymers used for the lid and exterior.
If you need a bottle with much longer heat retention and a more rugged steel build for school, the Han's Bottle 12oz is a stronger alternative.
