How Do You Protect Ayu Stuff?

[Mad_Cactuar]

I don't see the reason of buying it, copying it, and keeping it on the altar. Unless of course you're an obsessive collector. Just use your original copies, except be careful like Kodayumi said. Her stuff aren't cheap, so I'm sure you realize the value of them all and take utmost care.

Don't touch the surface of the CD, always put them back in the cover, don't leave them lying around, handle the booklet carefully, don't remove the booklet and leave it around, etc.

A scratch isn't the end of the world too, light to medium scratches won't even affect the CD at all, it's the deep and very visible ones that are dangerous. Just be careful.
