Do NOT get distracted and leave your beautiful pens with gorgeous celluloid bindes in a water bath for several hours. I am too sad and ashamed to post a picture of my White 400 Torty Pelikan. The binde shrank and seam pulled away near the section. Of course, the pen will still write. Of course, if you don't look at that side of the pen, it's still a beautiful pen. Looking at the seam side of the binde, however... sadness. (pics added below for education of others despite my shame)
