I order these in one box at a time so they're always fresh. These are the best suction cups for hanging your stained glass sun-catchers. Always make sure you have a firm hold before hanging your project and check them often because the temperature fluctuations can cause them to loosen. You will receive 100 large suction cups.
Please note: one of my distributors calls these 1-1/2 inch the other 1-3/4 inch.
