What to know before buying

Listing details to confirm

Listing dimensions are inconsistent: the sleeve is stated as 12.75” x 12.75” and 32.5 x 32.5 cm, while the separate product-dimensions entry is 33 x 33 x 1 cm and 390 g. The listing also alternates between a 3 mil thickness and its parenthetical metric conversion. Confirm the sleeve dimensions and thickness format if an exact fit matters. These are listing discrepancies, not confirmed product defects.

Who is it for?

A good fit for

Record collectors seeking clear outer covers for standard single and double 12-inch LPs.
Buyers who want a small pack for protecting or displaying selected records.

Less suited to

Collectors who need confirmed sizing for unusually thick sleeves or gatefold jackets without checking the stated dimensions first.
Buyers seeking inner record sleeves rather than outer album covers.
