Dede recommends having these on hand for emergency's or for when your pet parent client has a hot spot or for injury.  Dede is not a Veterinarian.  All Sales Final.  Each package has 3 pieces. It's best to be prepared and Dede loves this product.  To get a kit of all types she carry's check the Groomer Kit Section of our website.  All Sales Final.  This company mandates prices, so if you see something cheaper, it is not allowed and you can let me know so I can share that information with Pawflex as I order direct from Pawflex.
