Price is not negotiable. Shipping will be via Yu-Packet Post Mini or Yu-Packet Post. The pump is no longer usable, so I replaced the main unit and am selling only the parts. Operation confirmed. Returns, refunds, and complaints are not accepted. Please refrain from purchasing if you are concerned about the condition of the item, such as signs of use, scratches, paint peeling, or dirt, as it is a used item and has been stored at home. Please only purchase if you understand that this is a used item. Please note that there may be differences in color between the photos and the actual item due to amateur photography. Priority will be given to those who purchase immediately. Thank you.
