Caviar is known as the "black gold" among ingredients. With plump roe grains, it features rich mellow aroma and delicate texture. Extremely delicate in flavor, it is vulnerable to oxygen, moisture and light, which easily cause aroma loss, grain softening and oxidative deterioration. The aroma preserving vacuum caviar tin is tailor-made for the storage and packaging of high-end caviar.

Equipped with a fine inner protective coating, it is anti-corrosion and anti-seepage, suitable for cold chain storage and low-temperature fresh-keeping scenarios, and supports caviar packaging in various specifications from 10g to 500g.

　　Exquisitely crafted, the tin box has smooth and burr-free edges with smooth opening and closing and tight closure. Its compression-resistant and wear-resistant structure resists extrusion during transportation and daily collisions, effectively protecting caviar grains from breakage. Meanwhile, it supports personalized appearance customization with high-end processes such as gold stamping, embossing and matte finishing, presenting an ultimate luxury texture.
