Twill binding covers were originally introduced by GBC as a premium option for organizations that were looking for a highly elegant and professional look and feel. Made from paper, they have a very tightly embossed vertical lineal pattern (small lines that run from the top to the bottom of the cover). This pattern gives the sheets a wonderful texture and really helps them to stand out from the crowd. Over time most of the colors of twill have been discontinued, however we still carry white and have some inventory left in a selection of other colors. Check them out below.
