Material advantages

Premium 316 Stainless Steel

The cup is made from 316 stainless steel, a premium material known for its excellent durability and corrosion resistance. The stainless steel construction provides a strong and reliable option for everyday beverage use while giving the product a clean, premium appearance.

The double-wall construction provides an additional layer of insulation between the beverage and the outside surface. It helps maintain the temperature of hot and cold drinks for longer and reduces direct heat transfer to the exterior, making the cup more comfortable to hold.

Compact 300ml Capacity

With a 300ml capacity, this cup is compact enough for daily coffee, tea, milk, juice, water, and other beverages. It offers a practical size for people who prefer a smaller serving while remaining easy to carry and store.

The rounded eggshell-inspired body gives the cup a distinctive visual identity. Compared with conventional straight-sided tumblers, its soft curves create a more approachable and fashionable appearance, making it especially suitable for modern lifestyle and homeware collections.

The cup weighs approximately 145g, making it particularly convenient for everyday carrying. Its compact dimensions of approximately 8.3 × 8.3 × 10.5cm allow it to take up minimal space on a desk, bedside table, kitchen counter, or in a bag.
