I have now been apart of two drops with Boker pens. The first time was the aluminum bolt pen. Originally I was sent the wrong pen entirely (which the did let me keep) and then it took forever to finally ship the correct one. The second time I got the flame treated titanium bolt pen. This time my order was straight up cancelled weeks after the estimated ship date (Massdrop was kind enough to offer a $20 credit for the inconvenience). I don't know why the Boker drops are so wonky but beware!
