Borosilicate Double-Wall Flower Cup

Each mug has a height of 9.5 cm, diameter of 7.5 cm, and volume capacity of 300 ml. It weighs 280 g and is formed from pure borosilicate glass — known for low thermal expansion, high chemical resistance and optical purity. The double-wall architecture incorporates a fixed air gap, not vacuum, providing stable insulation without risk of implosion or seal failure. Real dried flowers are positioned between walls and permanently bonded during annealing — fully sealed, inert and visually preserved. The smooth exterior allows easy wiping and streak-free drying. Compatible with dishwashers (top rack recommended), microwaves (without handle contact), freezers and direct heat sources up to 150°C. Works equally well for steaming Earl Grey, frothy oat milk flat whites, chilled green smoothies or sparkling elderflower cordial. Designed for UK living patterns: compact enough for small kitchens, elegant enough for guest service, durable enough for daily rotation. Note: Due to natural material behaviour, minor internal moisture may appear near flower zones after extended hot use — verified as harmless and typical for authentic botanical encapsulation.
