Went and bought 10 packs today at the Daytona beach Harbor Frieght store.At first,I ordered them on line and then I decided to drive down and get them and save the S&H.The owner said that he had a room full. .I called and cancelled my on line order.They also have the those super grip suction mount handles for $6.99 each.They are exactly what they sell in the quilt stores for a whole lot more!!!!!These are blue and the ones for quilters are purple.There is no difference in them except the color!They suction to your rulers for those who may not know what they are.They are used on bathtubs as safety grips.
