I have used Nauk's Disk-O-File sleeves in the past when my collection was smaller and was growing slowly, a few disks or a few small collections added here and there. No complaints about them. Very durable.
Recently though, I have received about two short-box pickup truck loads of disks. This haul has been a bit overwhelming and has caused some marital stress, despite the spousal delight in many of the finds in this avalanche of records, finds such as the small cache of Al Bowly stuff.

Many of the disks here require re-sleeving. Most of the sleeves are foxing badly and are self-disintegrating and contaminating the records with fine paper dust. Shelling out for Disk-O-File sleeves here would be very expensive. I would need a very large number of them. Shipping would be costly to Canada, and the dollar value of the order would bring the shipment to the notice of Canada Customs, with such attention greatly delaying package delivery and greatly adding to the cost with duty taxes and service fees for charging the taxes.
Also Nauk has been out of 12" sleeves for quite some time,
Can anyone suggest reasonable alternatives? Thanks.
