Travel mug Bialetti STRTH01A 900 ml — Black and Red, stainless steel interior

Bialetti STRTH01A is a 900 ml travel mug with a stainless steel interior and a black-and-red exterior inspired by the Stranger Things Capsule Collection. The double-wall construction provides thermal insulation for hot and cold beverages, while the design includes a handle and a reusable straw. A glow-in-the-dark effect reveals the Demogorgon motif when the lights go out.

Advantages

The 900 ml capacity suits long commutes, workdays or outdoor activities, reducing the need for frequent refills. Double-wall stainless steel construction helps maintain beverage temperature and improves durability compared with single-wall alternatives. The handle and integrated straw add convenience for drinking on the move, and the glow-in-the-dark Demogorgon motif adds a distinctive visual element without affecting functionality.

Suitable for

• Commuting and travel — large capacity for long journeys
• Outdoor activities — durable stainless steel interior
• Office and workdays — keeps drinks hot or cold at the desk
• Fans of themed merchandise — Stranger Things-inspired design

When it may not be suitable

This travel mug is relatively large at 900 ml and may be bulky for users who prefer compact or pocketable bottles. The decorative glow-in-the-dark finish is aesthetic only and does not affect insulation or leak resistance.
