TWSBI Diamond Mini AL Fountain Pens

The TWSBI Diamond Mini AL fountain pen is a reiteration of the original TWSBI Mini fountain pen that features the addition of aluminum parts. A mini pen, that performs like a standard-size pen when posted, the Twsbi Diamond Mini AL is a top choice for newbies and experienced fountain pen fans alike.

This small piston filler fountain pen has a stainless steel nib with a crystal clear demonstrator resin body. Its compact size makes it easy to carry, and the length extends when posted for easy, comfortable writing. And since it's a smaller pen, it's not heavy, so it's comfortable even for longer writing sessions. The addition of the aluminum parts for Twsbi's AL Diamond Mini provides a higher-quality look and feel to an already fantastic pen design. The Twsbi Diamond Mini AL fountain pen is sturdy, well-made, steady in the hand, and a beautiful writer. The piston filler is smooth and sure, like other Twsbi pens, you can swap out the nib unit if you want to try another nib size without purchasing a second pen.

The pen design has a very stable post as the cap is designed to screw onto the threading at the back of the barrel (without affecting your piston knob). Both ends feature a small o-ring that creates a very snug seal when you cap or post your pen cap on your Twsbi Diamond Mini AL fountain pen.

Twsbi fountain pens are one of the most affordable options if you want to try out a piston filler fountain pen.
