You're looking for a quick letter-writing fix and I gotta tell you, grab some of this Midori stuff because you really can't go wrong. We've got alpacas, capybaras, quokkas. Whatever freaky animal you're into. Just write a letter already.
You can't see em through the internet, but the stickers on these Midori letter sets are those weirdo textured stickers. That's right: the extra special ones that you would save for the sickest spot in your sticker book. Maybe even cover material.
