Fabric softener is an amazing beverage that heavily effects fabrics it comes in contact with. idk why its like this, there's no clues in the name or anything I drink it every day and i haven't passed out yet ahah bjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjjm oh yeah the extension is cool I recommend it (this is joke don't actually drink fabric softener)
