I'm very protective of my collection, so with how many CDs are released in digipaks without a proper tray nowadays, these sound like a great idea on paper. Unfortunately, there are bad batches of this item here and there, and you won't realise it until it's too late and the damage is done beyond repair. They can leave a cloudy warped residue on the playable surface of the disc, that could not be cleaned off with fluid and a microfibre cloth. I've had dozens of valuable discs damaged by this, from now hard to find Japanese pressings of The Beatles, and Radiohead, to various other stuff that cannot be replaced. Better off leaving them in its original packaging with the potential minor scratch that a clouded up disc.
Nagaoka Anti-Static Inner CD Sleeves (20-Sheet Set) Customer Reviews
Audio Accessory
I can no longer recommend these sleeves. I was shocked and horrified to discover that, as another recent reviewer recently warned, these sleeves are leaving marks/residue on the recorded side of my CDs. I had to use a microfiber cloth and isopropyl alcohol to remove the residue. It was a very time consuming and frustrating to go through so many discs. My CDs are kept in a room with low humidity and regulated temperature. I won't be buying these again. At this point I think it's safer just to store the discs in the digisleeve packaging without inner sleeves.
I have previously ordered 13 packs (a total of 260 sleeves) of these since 2023, and to my dismay, I recently discovered that they leave visible and unpleasant marks on CDs. I’m not sure whether this is due to a chemical reaction or if some material from the inner surface of the sleeves is transferring onto the discs. The CDs have under no circumstances been exposed to high temperatures or humidity. They have been stored in a climate-controlled indoor environment typical of Scandinavia, under stable and safe conditions. It is therefore entirely out of the question that the marks could have resulted from storage conditions or any reaction related to heat or moisture. Could it be that these sleeves are simply no longer safe for CD storage? Has the quality of the plastic material deteriorated over time? This is really unfortunate. These products are purchased by customers who want to protect their CDs — yet the result is exactly the opposite. The manufacturer should take responsibility for this.
I would like to warn individuals about this product. When inspecting my CD's, I have discovered that the CD sleeve has damaged a lot of my CD's by leaving long spots on it by where the CD sleeve is touching the CD. Those can be seen by inspecting the CD under a bright light. I recommend everyone using this product to double check your CD'S!
