Custom OEM Metal Pens Manufacturer & Global Supplier














Eco-friendly bamboo ballpoint pen KR4012 — 135*10mm, 8.5g, natural bamboo barrel with chrome-plated metal fittings and a custom laser or silk printed logo. OEM/ODM manufacturer, MOQ 1000pcs, free pre-production sample.
The KR4012 is built on a genuine bamboo barrel with polished chrome fittings and a hand-finished surface. It is supplied mainly to B2B promotional campaigns, conference giveaways and premium client gifts.
Because bamboo is a natural material, no two barrels are identical — every pen has its own grain and node pattern.
Bamboo is a fast-growing grass rather than a timber, so the barrel is a renewable, low-impact alternative to plastic or metal.
Chrome-plated fittings keep the finish bright and hard-wearing, and the barrel takes laser engraving or silk printing cleanly.
We have produced this model for buyers in North America, Europe and Australia.
Size is 135*10mm and weight is 8.5g, based on the current production spec.

We show at Canton Fair and international gift fairs throughout the year. Factory visits can also be arranged — useful before committing to new tooling.
