No, there is no extra cost for general use of logo on lanyards. You can use only your logo or message, even you can use logo & message both on the lanyards. However, please note that if the length of the repeated unit(either message only or message plus logo) should be less than 230mm, or there would be extra imprint mold(s) cost. Also extra cost for multiple imprinted colors will be charged accordingly for imprinted style if needed.
