We work with several factories that produce top quality wood pens. They make pens from rosewood, walnut, maple, bamboo, and bi-wood (a combination of maple and rosewood). Their production capacities are huge, in the tens of thousands per month, and they can offer laser engraving of words or pictures on the barrel.
Custom wood pens could also be made.
If you’re in the continental US and would like to see a sample, I’d be happy to send you one free of charge. Just email me your address and I’ll get one out. This offer is good for 30 days after the date of this blog post.
