Generally comes from quadrupeds. Ungulates. Ruminants. Occasionally from reptiles or birds. Tough stuff. Smells nice. Affords protection to people and equipment. Doesn't melt. Hard-wearing. Not a petrochemical by-product.
When I buy something in good faith that is described more than once in the advert as "leather" I expect it to fall into the general description as above. I don't expect it to be "PU leather". PU leather is a creeping abomination. A cheap and nasty faux product that reeks like a pair of rubber gloves and has all the durability of a wet newspaper. In the UK at least, to try to pass PU leather off as anything other than the unpleasant con that it is is "misrepresentation".
As you may have surmised the postman brought me a parcel today. A spiffy new "leather" cover for my Tab, complete with a built-in Bluetooth keyboard. Sold from a very well known riverine online retailer who ought to know better.
I don't like plastic.
I don't like being misled.
I don't like paying for leather and getting plastic...
Trading standards are aware...
