Is this offered in black?

How can i get a replacement adhesive sticker? i have used this for 2 yrs but now it doesn't stick anymore. i just need another 3m adhesive tape

Do you guys make mice adapters for the small logitec mice too, the ones that come with the keyboard/mice combos? I like the mice but they are so small

does the white one discolor over time? turn yellow?
