# Comic bags and boards, 100 pack > A bag and a stiff board for each single issue. - Protection, Best value - Typical UK price: £14 to £22 (a typical band, not a live price) - Platforms: Whatnot, eBay, Vinted, TikTok Shop, Depop, Etsy - Orders a week: 0–2000 - Not yet checked by a person Buyers expect a comic to arrive bagged and boarded. The board stops spine rolls and bent corners in the post; the bag keeps damp out. ## Setups - [Comic back-issue room for Whatnot shows and eBay](https://sellersetups.com/setups/comic-back-issues-live): Long boxes, bags and boards, an overhead phone and board-stiffened mailers for selling back issues live in the evening and on eBay in between. ## Comic sellers who need bags and boards Bags and boards suit you if you sell single issues or short runs on eBay, Whatnot or Vinted. Clearing a back-issue collection gets through a 100 pack fast, while listing a few keys a month can make one last most of a year. Graded books and trade paperbacks need different packing. These are for floppy single issues, the format most comic buyers ask to see bagged and boarded in your photos. ## Matching the size to the era Comics come in different sizes by era, and bags are cut to match. Current or modern bags measure about 6 7/8 by 10 1/2 inches and fit most comics printed from the 1980s onwards. Silver Age and Golden Age books are wider and need their own bags. Current-size boards are slightly narrower than the bag, about 6 3/4 by 10 1/2 inches, so the comic and board slide in together. Choose boards described as acid free or buffered, and bags in polypropylene; Mylar sleeves cost more and suit high-value keys. Annuals and thick prestige-format books need a thicker bag. If a book strains the seams of a standard current bag, order the thick size for it. ## Bagging a book for sale and for the post Place the board behind the comic, glossy side towards the back cover, and slide both into the bag together, spine first. Fold the flap over the back and close it with the tape strip or a small piece of low-tack tape that does not touch the comic. For posting, sandwich the bagged book between two pieces of corrugated card cut slightly larger than the bag, then put it in a stiff envelope or a flat box. Weigh it before you buy postage and measure it against Royal Mail's size limits, since a comic plus card often sits above Large Letter size. ## Other ways to protect and post comics Use bubble wrap, 500 mm x 100 m, as a fallback for posting. It cushions knocks, but it won't stop a spine roll unless you bag and board the book first. A comic long box keeps bagged books upright at home. Bag first, then box, and the boards stop the books slumping in a half-full row. A 15 pack of double-wall boxes, 18 x 12 x 8 in, suits bulk lots of twenty issues or more, where envelopes would buckle under the weight. ## Cost and when to rebag At £14 to £22 for 100 sets, a bag and board costs roughly 14p to 22p per comic. On a £3 back issue that is a fair share of the sale, so bag only books above a price you set and sell the rest as lots. Polypropylene bags yellow and boards lose their buffering over the years. If you buy a collection in old bags, replace them before you photograph the books: yellowed bags dull a clean comic. ## Common mistakes - Silver Age books bend at the edges in current-size bags. Measure the comic and order the size for its era. - Fold the flap over and tape it to the bag, not the comic, or you leave residue on the cover. - A board in front of the comic hides the cover in photos, so place it behind the back cover. - Stiff card on both sides, or a flat box, stops spine rolls that a soft envelope lets through. - Rebag books before listing, because yellowed bags dull the covers. ## Questions ### Do I need to bag and board every comic? Buyers expect it for anything listed as a single issue. Low-value issues sold as a bundle can share a bag or go straight into a box. ### Which bag size fits modern comics? Current or modern size, about 6 7/8 by 10 1/2 inches, fits most comics from the mid 1980s onwards. Older books need Silver or Golden Age sizes. ### Which way does the board face? The white or coated side faces the comic. The board goes behind the back cover so the front stays visible. ### Are Mylar sleeves better than polypropylene bags? Mylar lasts longer and stays clear for decades, which suits valuable keys. For everyday stock, polypropylene bags cost far less. ### How often should I replace bags and boards? Check them every few years. Replace a bag that has yellowed or a board that has gone brittle, especially before you sell the book.
