My collection of old 45rpm records increased recently when I essentially inherited quite a number of old 45s which are still in their original paper sleeves. A friend of mine simply didn't want them anymore! Many of these 45rpm records have sleeves that are really nice with artwork that impresses me--and so these sleeves for protecting my "new" 45s are just what I need! I'm certainly not going to part with these original sleeves and their artwork to replace them with blank white paper sleeves which I also use for 45s that don't have their original paper sleeves anymore.
Each plastic see-through sleeve has enough room for the record and its paper sleeve; that way the paper sleeve doesn't get damaged by the plastic see-though sleeve. Moreover, the flat surface of these see-through plastic sleeves is easier to clean and care for; I don't have to worry about accidentally doing damage to a paper sleeve with its awesome artwork if I dust them or if I clean these plastic sleeves with a very slightly dampened cloth.
I highly recommend this product for anyone like myself who has those old 45s with the intention of keeping them in excellent shape for many years to come!
