The container is made of thickened black opaque glass, which blocks ultraviolet rays and prevents the stored items from oxidizing and becoming ineffective due to light exposure. The threaded bottle mouth is precisely fitted to the sealing cap, ensuring strong airtightness and preventing moisture and leakage. The high borosilicate glass is safe, non-toxic, acid and alkali resistant, and odorless. The thick walls are sturdy and drop-resistant, and the matte appearance is sophisticated and simple. Custom logos can be screen-printed. It is suitable for various light-protected storage needs such as health products, skin care products, Chinese medicine powder, coffee powder, and spices.
