Insulated Drinking Bottle THERMOS FUNTAINER BOTTLE Mermaid 0.35 L, double-walled stainless steel, PP cap

THERMOS FUNTAINER BOTTLE Mermaid 0.35 L is an insulated drinking bottle with a double-walled stainless steel body and a polypropylene (PP) cap. With a 0.35-litre capacity, this compact bottle is designed for everyday transport of cold or room-temperature drinks. The construction reduces heat transfer to help beverages stay cooler for longer than in single-wall containers. The bottle is lightweight and built to withstand daily use at school, work or outdoors.

Advantages

The double-walled stainless steel construction provides thermal insulation while keeping the exterior comfortable to hold. The PP cap offers a spill-resistant closure and is easy to open and close for quick access. The compact 0.35 L volume balances portability and practical capacity for children and adults who need a small bottle for short outings. Durable materials make the bottle resistant to dents and everyday wear.

Suitable for

• Children’s school bags and lunch boxes
• Commuting, office desk use and short business trips
• Light outdoor activities such as walking, cycling and park visits
• Travel when a small insulated bottle is preferred

When it may not be suitable

This bottle is intended for cold or room-temperature drinks and for short-term insulation. It is not sized for extended trips where larger volumes are required. The PP cap and design are optimized for spill resistance and everyday convenience but are not intended as a leakproof solution under heavy pressure or rough handling.

How to use

Fill the bottle with a cold or room-temperature drink and close the PP cap securely to help maintain the beverage temperature.
