This listing is for a box of United Drug Co - Medford Double Edged Razor Blades.   The box actually has 31 blades still in the wrappers.  There is a slot in the side of the box for used blades.  The box is in very good condition.  I will have other blades listed.  I will gladly combine shipping.  Please e-mail any questions.  I will gladly combine shipping.
