Frequently Asked Questions

Q: What makes these deep hole marker pens different from standard markers?

A: These waterproof marker pens feature an extra-long, slim nib (approximately 20 mm reach) housed in a durable metal barrel, allowing you to mark accurately inside deep holes, narrow slots, and confined spaces that a standard broad-nib marker simply cannot access. The permanent, oil-based ink bonds to metal, wood, plastic, ceramic, and more — even in damp or wet environments.

Q: What surfaces can the long head nib markers write on?

A: The permanent oil-based ink adheres to a wide range of surfaces including metal, wood, PVC plastic, stone, ceramic tile, glass, and concrete. Because the ink is waterproof and oil-based, marks resist moisture, making these markers suitable for both indoor and outdoor workshop tasks such as woodworking, plumbing, construction, and metal fabrication.

Q: How many markers come in the pack and can I choose colors?

A: Each pack contains 8 deep hole long head nib markers (Model 906). The product is available in 2 color options, so you can select the ink color that best suits your project or organizational needs.
