This 40oz tumbler design features a crisp white background adorned with a shimmering, holographic rainbow mermaid scale pattern.
The scales reflect iridescent hues—purples, pinks, blues, and golds—that shift depending on the angle, giving it a magical, under-the-sea vibe. The sleek stainless steel body is paired with a white handle and matching lid, keeping the look clean, vibrant, and fun. It's giving mermaid-core meets glam everyday hydration.
