Pigeon electric breast pump. It's an old model, but the replacement parts are compatible with the current model. Used for about six months and stored at home. Operation has been confirmed. Occasionally, the suction feels weak, but it returns to its original strength by reinserting or changing the direction of the silicone valve on the bottle side. There were no particular problems with its use. If you are concerned, you can purchase and replace the valve parts separately. *Price negotiations are accepted if you purchase with other items. No returns.
