Fashion icons Mary-Kate and Ashley Olsen have come under fire for using fur in their latest accessories line.

  The TV twins' clothing range The Row includes a new backpack made of animal pelt, which retails for $16,000.

The item has caught the attention of bosses at People for the Ethical Treatment of Animals (PETA), who have condemned the pair for using the hide of creatures in the name of style.

A spokesperson for the animal rights group says, "If it looks like a troll and acts like a troll, it's probably a Trollsen Twin - or someone wearing one of their new $16,000 totes, which are made from the fur and skins of innocent animals."

"What the Olsens lack in creativity, they try to make up for in shock value. Sadly, it's the foxes, calves, and alligators - who often have the fur ripped off them while they are still conscious and able to feel pain - who pay the dearest price."
