As you well know, for Macs there are many accessories and covers are no exception. Of course, we normally see very simple covers made of materials such as plastic or neoprene (I have one of the latter), but these are different.
These are retro covers that simulate old books, and it must be said that they are very successful and give an incredible effect, surely leaving more than one astonished when he sees us with a book of that caliber and then taking out the MacBook from within.
Of course, the exclusivity is paid and each cover goes to 80 dollarss, so price is also something to consider.
