It appears you have been sold a cheap Kryptonite rip-off. There appears to be no Kryptonite chains that are black, and all the coverings are cloth/fabric based, and NOT nylon sleeves.
If you bought it for security, then the Locks That Work thread would have advised against it. And if you bought from Ebay to save money, Evans and CycleSurgery do price-matching to internet shop prices. You have mystified me in this purchase.
