Mary-Kate and Ashley Olsen have designed a purse for charity.

The Fashion designer siblings - who have three fashion labels, The Row, Elizabeth + James and Olsenboye - have created the limited-edition change purse for their JCPenny Olsenboye collection to benefit Pennies from Heaven, a campaign that gives to after-school activities.

Ashley said: "Every child should have the opportunity to be part of a positive and nurturing environment after school."

Mary-Kate added: "Through the purchase of an Olsenboye change purse, customers can help support after-school programs and impact a child's life."

The purse, which features a peace sign, can be purchased exclusively at JCPenny for $9.99, with all proceeds going toward the campaign.

While they have created an affordable charity purse, the twins recently launched a luxury handbag collection for The Row.

The nine-bag line includes a day tote, backpack, doctor bag and shoulder bag made from python and alligator and are available from Barneys department store, New York.

Ashley said: "There are important style contributions from almost every era. Drawing on the right references at the right time is the key."

Mary-Kate added: "My problem is not with the trends themselves but the fact that trends are constantly repeating themselves."
