Smooth sea glass pebbles in graduated shades of green and teal stack into a balanced cairn against a pale aqua background, with small spheres and stones nestled beside the tower. The watercolor technique captures the translucent, weathered quality of beach glass, creating a composition that feels both meditative and gently playful. Built from double-wall stainless steel and made to order, holding 20 ounces with a snap-on lid, a standard-cup-holder fit, and wraparound artwork. Your commute carrying original art instead of another branded tumbler.
