Double-Wall Glass Coffee Mug Set with Decorative Flowers (2 Cups)

This set of two double-wall glass mugs features decorative artificial flowers permanently sealed between the glass layers, creating a unique visual effect with each cup. The borosilicate glass construction provides thermal insulation that keeps coffee or tea hot while the exterior stays comfortable to hold. The air gap between walls prevents condensation rings on furniture and maintains beverage temperature longer than single-wall mugs. Available in 250ml or 350ml capacity sets with various floral designs including red, pink, and black petal patterns. Each mug is handmade with real pressed flowers that are preserved between the glass walls, and the loose petals shift slightly when the mug is moved, creating different arrangements each time. The clear glass handle and smooth rim make it functional for daily coffee, espresso drinks, tea, or cold beverages. Key Features Double-Wall Thermal Insulation: Air gap between borosilicate glass walls keeps beverages hot for extended periods while the outer surface remains cool and safe to touch without burning hands. Decorative Floral Design: Real pressed flowers permanently sealed between glass layers create unique visual patterns, with loose petals that shift and rearrange when the mug is moved or tilted. Heat and Cold Resistant Glass: Borosilicate glass withstands temperatures from -20°C to 150°C, safe for hot coffee directly from the machine or cold beverages from the refrigerator without cracking. Anti-Condensation Construction: Double-wall design eliminates exterior moisture buildup and condensation rings, protecting furniture surfaces when using cold drinks. Comfortable Glass Handle: Smooth, curved handle provides secure grip and stays cool even when filled with hot beverages. Handmade Craftsmanship: Each mug is individually handcrafted with unique floral arrangements, making every piece slightly different in petal placement and pattern.

The 2 mugs in your set will have coordinating but not identical floral designs. Dimensions may vary ±1cm due to handcrafted production. Usage Tips Hand wash these mugs with warm soapy water and a soft sponge to preserve the floral decoration and glass clarity. Avoid dishwashers, as high heat and harsh detergents can damage the sealed flowers over time. The double-wall construction means less heat transfers to your hand, but always test the rim temperature before drinking hot beverages, as the rim is single layer glass. The loose petals between the walls will shift when you pick up or tilt the mug, creating new patterns with each use. For best thermal performance, preheat the mug with warm water before adding hot coffee or tea. Avoid extreme temperature shocks like pouring boiling water into a frozen mug, even though borosilicate glass is heat resistant. The clear glass shows coffee or tea color beautifully, but it also shows staining, so rinse promptly after use to prevent buildup. Do not microwave, as the sealed flowers and double-wall construction may not heat evenly.
