These Double Oversize Record Outer Sleeves are the biggest we carry at 13-1/2" wide by 13" tall. Made of only virgin first quality polyethylene - these are the highest clarity polyethylene sleeves on the market!
The sleeves are archival quality - safe for long term storage! The Heavy Duty 3 mil thickness is premium and helps keep your collection safe. They fit most box sets up to 1.25" (due to the inconsistent sizing of box sets over the years, there is no sleeve that fits them all, however this will fit most!).
