These were received when I purchased a lampshade. I tried installing one, but it's a bit too bright for my home, so I've decided to use different light bulbs. One is unused and unopened, and the other was used for about 5 minutes. For the opened one, adhesive tape was used to secure it to the lampshade box, so some tape residue is present (with some areas where the tape has been peeled off). Also, there is a tear in the packing material inside the box. There is no problem with the product itself, but please refrain from purchasing if you are concerned.
