This breast pump can be used both electrically and manually, and comes with a comprehensive set of accessories for convenience. - Type: 2-way (electric/manual) - Parts: Comprehensive set of accessories - Usage: Easy to switch between modes See photo 3: Red circles indicate items used. "☓" indicates items not included. Unmarked items are unused. I used the electric pump for about 2 months(^^) I used a Pigeon pump before, but this one suited me better and was easier to use! There are no noticeable scratches or stains, but there is some evidence of use. As a bonus, I'll include Kaneson breast milk storage bags: 100ml x 1, 50ml x 8, and name stickers. The large bag has been opened, but the breast milk storage bags themselves are unused. Thank you for looking.
