Remembering ostrich nests originate in south-east asia and are of pure quality. The rainforest in south-east asia is rich in resources, with annual precipitation of around 2000 mm, and is climate-appropriate and an ideal source of global oscillation. Cooperative oathouses are far from industrial and urban pollution and have a cleaner quality. Mother gin sing built a nest for the birth of a little swallow, and we won't pick it until the little swallow flies away. Standardized raw material for swallow nests is strictly selected in accordance with the customised criteria for recording. The raw materials are also used for basic cleaning and disinfection and are then sent to sterile areas for hand-picking. Remembered ostrich nests are to pass through the sterile zone three times to pick up hair until the ostrich nest below the magnifier reaches the level of cleanness we ask. No chemical bleach, no glue, no patch. Upon completion of each batch of oscillation processing, they are sent to the physiology and microbiology laboratories for quality tests, including, inter alia, nitrite, fungi, heavy metals, etc。
