Double Layer Fake Bubble Beer Mug

This novelty beer mug has a 420 ml capacity and features double-layer construction with a gel-filled inner layer. The outer shell is made of durable, food-grade plastic; the inner layer contains non-toxic, freeze-activated gel. Dimensions: approx. 12.5 cm height × 8.5 cm diameter; weight: 380 g. The mug maintains cold temperature without diluting drinks, as no ice cubes are needed. Its transparent double-wall design creates an optical illusion of rising bubbles — a playful, eye-catching visual effect achieved purely through layered geometry and surface texture. Designed for comfortable, secure handling with an ergonomic wide handle that fits naturally in hand. Ideal for home parties, game nights, barbecues, camping trips, or as a lighthearted gift for beer enthusiasts and prank lovers.
