The Black & Blum Insulated Travel Tumbler isn’t just another coffee cup with grand promises.

This 600ml powerhouse delivers what others can’t: true 100% leak-proof performance for any drink, from scorching coffee to fizzy sodas to craft beer.

Built with premium 18/8 stainless steel and advanced vacuum insulation, it keeps drinks hot for 6 hours and cold for 8 hours. The ingenious lockable lid opens and closes with one hand, giving you that satisfying ‘click’ confirmation while preventing accidental spills in your bag.

What makes it different:

• Genuinely leak-proof (not just “spill-resistant”)
• One-handed operation with lockable mechanism
• Clear Tritan top lets you see your drink
• Completely disassembles for thorough cleaning
• Fits standard car cup holders
• Perfect for hot coffee, cold smoothies, or even beer

Stop settling for “spill-resistant” when you can have leak-proof confidence. Whether you’re commuting, hiking, or just moving through your day, this tumbler keeps up without letting you down.

Available in Ocean, Olive, and Orange.
