Favorite Resealable Outer Sleeve Yet!

Glad I tried these as they are just as great as the brand I previously used but has been out of stock for months. The 3 mil are a bit easier to manage but these 4 mil seem more rugged. Crystal clear with a properly positioned and secure adhesive strip. Highly recommended!

Just a little too heavy sealing record.i think I would like a 3mill better for me. But they are good and heavy.

Records cover

They seem to be working great, must be careful with double albums. When inserting they will tear easily.

33rpm record holders are OK

33rpm record holders I received look OK. I did not yet have a chance to use them.

Good but wish they would go back to old design.

Satisfied but not like the ones I used to buy with the pink strip. Liked the pink strip ones better.

Great 4 Mil outer sleeves

They are a heavier weight than I am used to and I like It. Easy to slide album in and remove. Even a double!

4 mill outer vinyl record cover protection.

12 inch 4 mill is almost to much. better with 3 or 2 thick tape not holding flap down.
