The Estie has been an integral part of the revival of the new Esterbrook brand. It’s sleek and stately in the hand and a great writing instrument for everyday use and special occasions.

Introducing the Estie Sparkle.
This gem of a pen has had a glitzy makeover and is our most ambitious Estie to date.

As Esterbrook is committed to collaborations with US makers, for this limited edition Estie, they partnered with Tim McKenzie of McKenzie Penworks in Charlotte, NC.

Wanting to separate himself by making his product unique, Tim did what any innovative, forward-thinking, self-proclaimed science fair geek would do: he added diamonds to the mix! For real. Taking advice and knowledge from his mother, a GIA certified gemologist and his own research, Tim figured out the precise size diamond dust particles needed to allow his pen material to be machined effectively without losing the intense sparkle of the gems. The result is the patent pending Diamondcast. This material shines from within, catches the light, shimmers with each move of the hand across the page and has made a big impression on the pen world.

Since Esterbrook wanted to shout the Sparkle from the rooftops in the biggest way possible, this Estie is available exclusively in their oversize model. Each of the colors, Garnet, Montana Sapphire, and Tanzanite, are offered in a limited number of pieces and like the prized diamonds that they’re made from, they are ready to sparkle.

This oversized turquoise sparkling resin fountain pen has palladium trim and has a cushion cap closure. It can be inked with either standard international cartridge or converter (both included) and is equipped with the respected #6 JOWO German steel nib.

Esterbrook began manufacturing nibs in the US in the mid 1800s, but the 1930s were a period of importance, as they introduced their first interchangeable nib system in 1933. The interchangeable nibs gave the user many options for writing, whether in school, business, personal etc. Today, a similar system is reborn with the Estie and the specially engineered MV Nib Adaptor (sold separately). The MV adaptor delivers a vintage nib experience with a modern shape Esterbrook pen. You can fit any vintage Esterbrook nib unit into this adaptor, and use it with your modern Estie fountain pen.
