It is your responsibility to measure your Tone Poets, Mofi, Analogue Pros, Vinyl Moon, etc, in both direction and include the spine thickness when selecting a sleeve. These record albums are notoriously all over the map with size!Please note that the Tone Poets, Analogue Pro, Mofi One Steps, Acoustic Sounds/Verve Series and the such, may not fit in this product or may be to heavy to keep the flap in. You may need the bigger 13 inch sleeves DP4R13CPP, available here or the 12 inch version DP4R12CPP, available here.
This design is meant to protect your album cover while still giving you easy access to the vinyl record. The album pocket has a 2.25 inch tuck-able flap for each pocket, to give you a perfect archival seal. I don't recommend storing your record in the pocket without a good inner sleeve.
CPP sleeves have excellent properties:
- clear transparency;
- heat resistance;
- and moisture proof.
CPP (cast polypropylene) film has a clear advantage over standard BOPP, polyethylene, Mylar or PVC sleeves.
What are the advantages of cast polypropylene? CPP has higher tear and impact resistance, better cold temperature performance and moisture transmission properties than standard sleeves. CPP won't turn cloudy over the normal life of the product, unlike other films. CPP is very hard to crease unlike BOPP and has some stretch forgiveness.Cast film is usually used in applications that require superior optical properties such as gloss, transparency, surface smoothness, and good tear resistance.Are they a little pricey compared to other low cost sleeves? Yes, but they are a true premium product to protect your expensive, irreplaceable record collection for years to come. No other product will give you this amazing clarity.
