Used for about 2 years! Includes the instruction manual, a baby carrier cover, drool bibs, sunshade hood, and storage bag as extras! It's reversible. The covers cost about 5000 yen in total, so I think it's a good deal for those who need them. If you only need the covers, I'm happy to sell them separately, so please let me know in the comments.
