I bought the medium size in 14k gold. One pad was good but the other had a hole in the back for the pen to go through. I bought these as a gift for a girl who loves sports and the whole idea was to protect her from the sharp end of the pole. She also loves to sleep on it. They seem to hold up well on a standard sized pen. Shown are typical standard 20 CZ Walmart earrings. I measured the thickness and length of the pins on these earrings for comparison. The thickness of the pins in the photo is 0.033 inch or 0.85 mm. The length of the pins in the pictures is 0.415 inch or 10.55 mm. to see if I can find a replacement for a hole in it. I will continue. Follow-up: 1 day later: timely customer service. The company will take them back but they said to order a large size if I want the pen to be fully covered in silicone. What I think I'll do Overall I think they work great. They're comfortable and extra flattering for people with thin earlobes who need some support behind the earring, but the standard plastic earbuds are too big. It's nice to sleep too. I would recommend them but they are a bit pricey.
