Pros: These are wonderful one use pippettes, conveniently stored in a cylinder plastic container. Makes for easy storage.

Cons: The only con is the plastic storage container that cannot withstand the test of time, or the post office (mis)handlers. I will have to store them in another means; probably a big ziplock baggie. This is a very small con.

Overall Review: I found this to be such a super deal that I have shared this offer with forum members/groups I belong to. The only thing that makes a great deal better is being able to share it with others.
