I bought one of the clear acrylic Gama Jumbo demonstrators from Asapens, and it's been a very nice writer from day one. Here is a photo (copied from their site): http://asapens.in/eshop/image/cache/data/GD-01-500x500.JPG I have had it for a few months now and use it regularly. And with use have come the scratches - inside of the cap, and nowhere else. The cap is scratched from all the way to the top of the nib to the rim. I've contacted Asapens and they have offered to help remedy the problem, but it will take time. To begin with, shipping to and from India takes, on average, 3 weeks - it's not unusual that it takes longer. Add the time to work on the problem, and it looks like I'd be missing my pen for at least two months. I am adding a picture of the cap only. I am asking for suggestions as to how I might fix this myself, in order not to have to send my pen away for fixing. If it is not doable with simple methods then I will avail myself of Asapens offer, which I find very generous. Thanks in advance for your thoughts and suggestions.
