The danger of the Retro 51 is that, whatever you are interested in, there's a Retro for it. And if you're interested in a lot of things, you're going to need a lot of Retros. That's why they make such good wedding gifts. And if you're out shopping for wedding gifts, you should probably treat yourself.
The Met editions are a bit more pricey than a standard Retro 51 Rollerball. This edition sells for $78 at Anderson Pens. I resisted it for months in numerous online ads, but seeing it in person was a mistake I'm glad I made. That's a lot for a rollerball. Most Retros fall around the $50 mark, which is about right for a "nice gift pen" cost. The Met set is officially licensed, though, which naturally increases the price--and some of that total goes to support the museum. In my experience with Retros, you find the one or three or twelve that are right for you, and then you try not to look at the three or ten or fifteen other Retros that came out that week.
In short, these are my favorite pens to gift, to others, and to myself. They're fun to collect and fabulous to write with. The Met series is beautiful, perfect for art lovers, and this William Morris print is up there with my favorite Retro designs of all time. I keep saying I don't need more Retros, but Retro 51 keeps proving me wrong. I'm glad.
