Pastel Relief World Map – Personalized 保温保冷タンブラー

A soft pastel relief world map wraps around the bottle, showing land elevation and ocean depth through gentle color gradients and shaded terrain. Based on ETOPO global elevation data, a widely used cartographic dataset, the design represents the shape of the Earth both above and below sea level. The “Adventure awaits” prompt and name field can be customized or removed, making it a thoughtful personalized gift for travel and map enthusiasts.
