This is a manual breast pump designed for comfortable and efficient milk expression. It features a nipple suction mechanism (likely including a flange) to draw milk. Often referred to as a 'susu' (likely a local term for breast milk) breastpump or 'nipple suction pump', this manual pump provides an alternative to electric pumps, offering portability and control over suction strength. The inclusion of '手动吸奶器' suggests the product is targeted towards a Chinese-speaking audience and translates to 'manual breast pump'. 'MB6' is likely a model or product code.
