It has plenty of stickers, so if one falls off, gets dirty, or comes off, you have a backup. For two months now, it has been in my pocket, bag, and it hasn't come off.

They are cut properly, neither too big nor too small in diameter, and they do not obstruct the camera's resolution.

Very good price and quality.

I wore them after my phone was already protected by a case, purely to avoid scratches, etc. that may occur from a bag or pocket. They don't stick 100%, I have noticed that they move if you apply force. However, none of them have come off so far, I drag them with my finger and they come back. Also, I haven't noticed any impact on the photos. Because the camera is protected by the case and I wanted them as an extra, I would buy them again (after all, the package has enough pieces for 3 applications). Without the case, I wouldn't buy them, nor would I rely on them, I would want something else to better protect the camera.
