Hi, I've been looking to buy a pen case for my Carlo Collodi edition & Gaius edition but I'm finding it difficult to get a case that suitable for such thick pens. My budget is 50$ as I've already spent money on the aston 2 pen case - but the pen doesn't go in smoothly and fits very tight (I'm scared it might discolour the pen) Would anyone have any recommendations? I was thinking of the Franklin-Christoph 1 pen case, but it says max diameter is 0.75" which is pretty much the same as the carlo collodi's width. http://www.franklin-christoph.com/1-2-3-pen-cases.html Thanks for your help!
