About This Product
The Titanium Bolt-Action Inkless Pencil is a 7g, 45mm closed TC4 titanium writing tool with a brass bolt-action mechanism, graphite alloy inkless tip, and integrated keychain loop — laser-engravable barrel, 2 spare tips included, MOQ 100 units, for EDC corporate gift sets and compact travel programs.
A compact EDC writing tool — TC4 titanium body, 45mm closed, 59mm extended, 7g. Push the brass bolt-action button to extend the graphite alloy tip; pull back to retract. The tip writes without ink: contact with paper transfers graphite particles, leaving a permanent grey line on standard uncoated surfaces. Two spare tips ship with each unit. An integrated lanyard loop at the tail mounts to keychains, carabiners, or zipper pulls. Titanium barrel laser-engraves for logo or text. For EDC corporate gift sets and field-use programs where a desk pen is too large.

How does the graphite alloy tip write without ink?
The graphite alloy tip is dense enough that paper contact transfers microscopic particles, producing a permanent grey line on standard uncoated paper (notebook, A4, kraft). Mark intensity is lighter than ballpoint but permanent — does not smudge once deposited. Does not perform on coated or glossy surfaces.
Can this mount on a standard keychain?
Yes. An integrated lanyard loop sits at the tail. Closed length is 45mm, compatible with standard keychain rings and carabiners. At 7g, it adds negligible load to an EDC carry.
What happens when the graphite tip wears down?
The tip unscrews from the nose using a standard thread interface. Each unit ships with 2 spare tips. For bulk orders, additional tip sets can be included in the initial shipment on request.
Is this appropriate for desk gift programs?
At 45mm and 7g, this pencil is sized for EDC and field programs rather than desk gifting. It pairs with compact tool kits, travel pouches, and outdoor or field-use corporate sets. For desk programs, the WP-109 Solid Brass Inkless Pen or WP-110 Solid Brass Hexagonal Ballpoint Pen are a closer fit.
TC4 titanium in compact EDC writing tools
TC4 (grade 5) titanium is the standard alloy for EDC writing tools in Chinese precision manufacturing — lighter than stainless steel at comparable strength, corrosion-resistant without plating, and holds laser engraving cleanly. At 7g, this pencil carries indefinitely on a keychain without noticeable load. The brass bolt-action mechanism adds visible material contrast against the sandblasted grey titanium body, and the mechanical action is more reliable than clip-cap designs at this scale.
Graphite alloy inkless tips: practical parameters for corporate programs
Graphite alloy tips leave a permanent trace on uncoated paper at a grey tone comparable to a 2H pencil. The mark is not erasable. Tips wear to a rounded profile with use; two tips per unit covers typical corporate program duration without reorder. For extended-use programs, including additional tip sets in the initial shipment avoids procurement friction later. The inkless format is a practical argument for briefs specifying no-consumable or low-maintenance writing tools.
