The M400 Tortoise all on it's little lonesome.

Top: Pelikan 120 school pen. Vintage pen with great semi-flex nib.
Left-to-right:
M200 Telekom (made for a corporation. Sometimes sets can be found. Wish I'd bought one when I saw it on ebay a couple of years ago.)
M200 Grey marble. Pre '97 style.
M400 Blue Stripe. One of my favorite writers - perfect with DC Blue.
M200 Green translucent. Doesn't get used a lot - nice pen but never jumps out of the box.
M200 green marble - that one. The one that is used every day.
M400 White Tortoise (or "Honey"). IMO, the most striking of the lot. I spend a lot of time admiring it.
