Obviously this is during Post Office opening hours. Each one is inspected before being posted. One way valve removed and packaged separately, to ensure you receive the pumps in perfect condition.
From time to time I may have one or two that have no box or imperfection that won't affect its performance but not to my high standards. A discount price could be had.If you are interested in one of these. Please message me first and I'll be able to tell you if I have any.
