Search for SKU, if match then copy description from 1 Workbook in another

Hey guys, I'm working with two workbooks. Book1 needs to search Book2 for a matching sku. If a match is found, then copy description in book2 over to book1. I had this working with VLOOKUPS but unfortunately I need it to leave the description alone if no matching sku is found.. so VLOOKUP is not ideal for this situation. I'm still new to all of this and was hoping somebody could help me with a macro. I've attached the sample files. Thanks!
