This is a manual breast pump designed for mothers to express breast milk. It features a manual operation, allowing for controlled suction and pumping speed. The pump offers 3 adjustable levels of suction, enabling users to customize the pumping experience based on their comfort and milk flow. It is likely compact and portable for on-the-go use, and may be compatible with standard baby bottles for easy feeding. The branding indicates it could be marketed under either the 'Real Bubee' or 'Cmbear' brand name, potentially suggesting rebranding or a shared product.
