78 Sleeve Durability

[chuckmoy]

I have made an interesting but obvious discovery recently. Many of Chinese 78s made by the Columbia and Pathé companies are much more durable and do not rip because the edges are sewn together, which prevents the regular ripping on most cardboard and paper 78 sleeves. It would be interesting to apply this method to other sleeves and see if it prevents the creation or expansion of tears.
