## Before you buy

- 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.

## 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.
