The latest victim of the retail apocalypse? Birthday cards.

Papyrus, the greeting card and stationery chain, will close all its stores in the United States and Canada after its parent company filed for bankruptcy, another casualty of the long-running decline of mall-based retail.

Schurman Fine Papers, which operates 254 stores, including the Papyrus brand as well as the American Greetings and Carlton Card chains, filed for bankruptcy protection on Thursday. All three store chains will close, but the branded cards they sell will still be available at other retailers.

“We regret that we are closing all our stores,” Papyrus wrote in a message on its Facebook page. “We hope that through our artistic, thoughtful greeting cards and our personal expression products that we were able to inspire you to celebrate and honor the special people in your lives.”

In its filing, Schurman Fine Papers said business had declined as part of “the general downturn in the brick-and-mortar retail industry.” In recent years, greeting-card sales have dropped and retailers have cut back on the amount of aisle space devoted to paper cards, as consumers switch to digital alternatives.
