Frequently asked questions
What's the best way to preserve comics?
The classic collector combo: an acid-free sleeve that shields the comic from dust, moisture and scratches, plus a rigid backing board inside the sleeve that keeps it flat and prevents creases. Our sleeves are acid-free with an adhesive closure; complete them with Fanatiko Backing Boards (Current Size) for long-term preservation.
Which size do I need?
Current for today's single issues, Big if they feel tight, Regular for the 70s and 80s, Silver and Golden for Silver Age and Golden Age books, and Magazine for large formats and magazines. Measure your comic and, if it doesn't fit, we'll refund your money.
Why does acid-free matter?
Acid-free material prevents paper from deteriorating and yellowing over time, which is why it's the standard for safe storage and long-term preservation. Its distortion-free clarity also lets you enjoy the covers while they stay protected.
How long does shipping take, and what if I'm not convinced?
In-stock items leave our warehouse in Spain within 1 to 3 working days, with free shipping on orders over €30 across Europe. You have 14 days to return your order, no questions asked, plus a 90-day warranty against manufacturing defects. Reach out via our contact page and we'll sort it out with a replacement or refund.
