So it's definitely more gold and blue not gold and purple like the photo shown here but the ano is really well done and bright. It's a threaded cap that on my model ever so slightly clocks just past perfect alignment when tightened, 1 1/4 turn cap that does post on the end when unscrewed. Carbide tip in the end for glass breaking if you're feeling brave or it's really necessary. Uses a parker type refill which ifs great for reliability and availability. Very happy with this pen and will be buying more Twosun pens as they become available.
