Assuming the stickers (i use Avery brand clear labels, 20/page i think it is, that I wrap onto both sides of the stiff tag) are printed with a laser printer to melt the toner into the plastic of the sticker, in sunlight the stiff tag gets brittle and usually breaks apart before the sticker is unreadable. Occasionally the stickers will start to come loose from the tag over the years. I try to bury them if I want em to last longer. I find black "wax" markers such as Listo brand ones are about the longest lasting for handwritten. There red did not last well at all for me.
