Mesmerizing Rainbow Jellyfish Black Coffee Mug — Vibrant Rainbow Design (11oz & 15oz)

The jellyfish design on this mug is a beautifully mesmerizing swirl of rainbow colors. Bright, joyful, and unapologetically bold — this glossy black ceramic mug brings a burst of color to slow mornings and late-night creative sessions. A deep black background makes the saturated rainbow spiral artwork pop, like a tiny celebration in your hand. It fits easily into a cozy routine: reach for the comfortable C-handle, sip something warm, and let the playful pattern nudge you toward curiosity and color. Durable glazing keeps the design vivid through dishwasher cycles, and the microwave-safe ceramic warms drinks without fuss. For people who collect color, sketch with their thoughts, or enjoy an energetic accent on a minimalist desk, this mug adds a little daily delight. The product is printed on demand and cannot be returned or exchanged.
