Imagine a tumbler featuring a vibrant watercolor design of an eyeball.

20 oz stainless steel tumbler. The eyeball itself is depicted with a large, expressive iris in shades of blue and green, blending seamlessly into each other. The pupil is a deep, inky black, providing a striking contrast to the lighter colors around it. Surrounding the eyeball, the watercolor effect creates a burst of colors—pinks, purples, yellows, and blues—radiating outwards in abstract swirls and splashes. The colors have a soft, fluid quality, characteristic of watercolor art, with some areas more saturated and others fading gently into the white background of the tumbler. The overall effect is both bold and delicate, making the tumbler an eye-catching piece of art.
