My Lamy 2K (Makrolon) suffered a weird injury: as I was screwing the barrel onto the section, the threaded part of the barrel broke off in the section. Doh! Based on the Lamy USA warranty, I packed up the pen to Texas with a note of explanation. I was concerned that they would consider this pen "abused" in a way that would void the warranty. Fortunately, and to the continuing credit of the company, they did not. They replaced the broken pieces — the barrel and the grip section — and retained the (undamaged) nib, feed, cap, and fill mechanism. Brilliant! I received the pen today, just 2 weeks after shipping it off (the website says to expect 3-4 weeks). Thanks, Lamy! Another satisfied customer.
