Mofi, don't know if you're refering to Sleeve Town/Sleeve City's "Diskeeper Ultimate Audiophile Inner Sleeves" mentioned in Myles' article, but I wasn't impressed with them. They could be fantastic sleeves for the money but they were designed/manufactured just slightly too narrow so that when you slide the LP into them they will often split. I've had to tape the split seams on more than half of the sleeves I bought. They don't always split the first time you put a LP into them but it seems that eventually they will. Again, they have potential, but until they get the sleeve design and manufacturing corrected they aren't worth the savings compared to the Mobile Fidelity sleeves. If you do buy the SleeveTown sleeves, I'd only buy a small batch to start with to see if they've fixed them yet.
