Caffeine Molecules Classic Coffee Mug コーヒーマグカップ

This coffee mug features a caffeine molecular structure pattern on a blue gradient background. The structure consists of interconnected hexagonal rings made up of white spherical atoms connected by gray bonds. Each hexagonal unit is identical and arranged in a repeating pattern across the image. The spheres have a metallic, glossy finish that reflects light, creating subtle highlights and shadows. The bonds between atoms are rendered as thin gray lines. The pattern creates a tessellating effect where multiple hexagonal units interlock. The background transitions from a darker blue at the edges to a lighter blue in the center, creating a subtle vignette effect. The entire structure is in high detail, showing individual atomic bonds and spherical particles in sharp focus. The mug is a fifteen ounce classic mug.
