I bought your clear mini hooks, 17006CLR-18ES to hang some art on my wall. The objects are carved wooden masks weighing less that .5 lbs, which is why I selected these hooks. I followed the directions to a "T" - wiped down the wall with rubbing alcohol, allowed it to dry, pressed the strip for 3o seconds, (my husband timed me), and then pressed the hook onto the sticky strip for 30 seconds. After one hour I hung my masks. Two fell about 3 weeks later, damaging them. They are not easily replaced as I bought them in Guatemala. I will not be buying these items again.
