Ancient Kauri

It's called ancient kauri, and it's up to 50,000 years old. Yes, 50,000! The oldest workable wood in the world, ancient kauri shows just the earliest signs of petrification. Called "whitebait," this phenomenon creates small veins of mineral deposits that give the wood a one-of-a-kind luminescence.

50,000 years ago, in what is now Northern New Zealand, a major natural event felled huge forests of kauri trees that had been growing for some 2,000 years. This event also created bogs in the area that protected these giants from the elements. Today these trees are typically found under farmland from which they are carefully excavated before the ground is returned to its previous contours.

Just for some perspective, here are a few things that happened on Earth less than 50,000 years ago…

  • 16,000 years ago the depressions that would become the Great Lakes were fully formed.
  • The last Ice Age ended approximately 5,000 years ago.
  • Homo Sapiens reached the area from which these trees were recovered only around 40,000 years ago.

Bog Oak

No, this wood isn't stained black. 5,000 years in a peat bog in the Ukraine have naturally turned these huge, ancient oak trees black all the way through.

At the end of the last ice age rising water levels caused huge oak forests throughout Europe to die standing and fall into the muck. For the last 3,500 - 5,000 years these trees have been preserved in anaerobic conditions underneath peat bogs.

The ages have turned bog oak a deep black with dark brown grain. This is the result of a chemical reaction that occurred between the tannins in the oak and soluble irons present in the bog soil.

How long will my order take to arrive?

Our products are handcrafted, mostly to order. We make our smaller pieces in small batches of 10-20 items at a time. Because of the custom, handcrafted nature of our products, it usually takes us 2-3 business days to prepare your order for shipment.

Estimated shipping times begin when your order is shipped and vary by the carrier and service you choose.

Love this pen. Materials and design are user friendly. Unique. Really like the way the cap screws onto the back when you’re using it.

I've had one Dynamo/Rollerball for 6 years

I bought the 1st Dynamo in 2017 and in 2019 we moved from Miami, FL to Jonesborough, TN and I lost the pen. I bought another one within a couple weeks. Couple months later I found my 1st one. So, now I have 2 to split between. Even though I've been retired for almost 5 years I still carry one of the pens in my shirt pocket. I use food grade mineral oil every 6 months to make it sleek. I have received many compliments on these pens. I bought my father in law a pen that was made from the deck of the USS North Carolina. I also bought my friend who runs the office at her husbands business a pen that I can't remember the name of. She is very possessive of that pen too!!! Quality products and supporting smaller businesses. Greg

My favorite pen

I have owned this pen for years and carry it with me everywhere (it pairs nicely with my Frost Journal!). The woodwork is gorgeous and smooth in hand, and it is nicely balanced for a great writing experience. I bought a second one for my grandfather who is a carpenter - he loves it as well!
