As part of a series of celebrity charity auctions launched by eBay and New York Magazine’s The Strategist, the Oscar winner is offering up one of her favorite things: a Shoo for Good bug-repellent shawl she apparently buys in bulk.

“This shawl repels mosquitoes. It really, really repels them. It’s very practical, and I feel it kind of goes with everything, which is another reason I like it,” Zeta-Jones, 50, told The Strategist.

“I have the shawls in lots of colors, but the cream one I’m donating was my first — the one my book curator gave me. Anyone can wear it; you can put it around your neck, or you can drape it around your shoulders. Michael [Douglas], my husband, even has one in navy blue.”

While Shoo for Good’s shawls — which are “enhanced with odorless, invisible, EPA-registered Insect Shield protection,” per the company’s website — typically start at $140, bidding on Zeta-Jones’ began at just $50. Plus, it comes with a personalized touch.

“I signed it — I hope you want my signature on it; if not, you may have to cut it off,” the “Mask of Zorro” actress said.

Other standout items up for grabs in The Strategist’s celebrity auctions — which will run through August 19 — include a vintage Betsey Johnson wedding dress, a signed copy of Erika Jayne’s coffee table book, Denise Richards’ gown from the “RHONY” Season 9 opening credits and Cheryl “Salt” James of Salt-N-Pepa’s custom denim jacket.

All proceeds will go to the NAACP Legal Defense Fund, with eBay matching all funds raised.
