Hello Kendra,
No, these blades will not fit the Panama XLP. These blades are made to fit the newer medallion style blade holders Casablanca is now using on most of their fans, not the old pretzel looking type that came with the XLP Panama. Do you own the XLP Panama or are you planning to buy one? The XLP panama is a discontinued fan and Casablanca stopped making blades for that fan over 2 years ago.
