I couldn't find specific information about the Raffini Hair Comb model SA40556-1. It's possible that this model is either discontinued, has limited online presence, or is available under a different name or number.

To assist you further, could you please provide more details or clarify the context in which you encountered this model number? For example, was it listed on a specific website, or did you see it in a store or catalog? Any additional information would help me locate the correct product description for you.
