30cm Straight, 4 pieces I am selling these as I will not be using this type. *No individual sales, price reductions, returns, or exchanges.* There are 3 pieces in the first photo and 1 piece in the second photo, for a total of 4 pieces. The second photo shows items I purchased as spares. The items in the first photo were given to me by the hospital and have been stored without being used. They were moved from one ziplock bag to another without being touched by hand, so they are clean.
