THESE TRIANGLES ARE WONDERFUL. I USE THEM FOR SEVERAL THINGS. WHEN WORKING WITH DRILLS THAT ARE CLUMPY I JUST PUT THE CLUMPY ONES IN THE TRIANGLES AND WORRY ABOUT THEM LATER. OR IF I SPILL MY DRILLS I CAN GATHER THEM TOGETHER WITH THESE TRIANGLES AND PUT THEM BACK INTO MY STORAGE JARS AS THEY CAN BE PICKED UP OFF THE FLOOR EASILY WITH THEM. These sell as singles.
