Lucy Hale, Ashley Benson, Troian Bellisario and Shay Mitchell are teaming up with DoSomething.org for a new PSA.

The Pretty Little Liars ladies are the new faces for the Staples for Students campaign, which encourages teens to collect school supplies for students in need.

From July 3 to September 17, teens are encouraged to collect school supplies and drop them off at their nearest Staples store to ensure they get into the hands of thousands of deserving kids just in time for back to school.

Lucy shared, “We are all thrilled to be the force behind this year’s Staples for Students campaign. After participating in last year’s backpack stuffing event and sharing my experience with my cast-mates, we all knew we wanted to be a part of this great cause to encourage teens to make a difference to help students start the year off right.”

If you’re a Staples customer, you can help too. By donating $1 or the amount of your choice, 100% of the proceeds benefiting local students in need. And each Staples store will be matched!

Additionally, Staples will donate more than $125,000 worth of school supplies to the program this year.
