Review on 🔪 OLFA 18mm Tungsten Tool Steel Rotary Blades & Marking Pen Set - Japan Import (Pack of 10) by Karla Richter

These are small, sharp #28 blades (check blade width in your rlotary) that quilters can use in their rotary cutters to cut blocks of quilting material. The blade can be used multiple times. After each session, before removing it, clean it carefully. Apply a dab of machine oil to the top and bottom while assembling the backing and you're ready to move on to your next quilt. These are good sharp blades that can be used multiple times if cleaned and oiled after each use.
