Frequently Asked Questions
Q: What makes this deep hole marker pen different from a standard marker?
A: The key difference is the extra-long 20mm pen tip that is designed to reach inside drilled holes, cavities, and narrow channels. Standard markers have short tips that can't access these recessed areas, making this pen an essential tool for woodworking, metalwork, and precision DIY projects.
Q: What surfaces can the deep hole marker pen write on?
A: This waterproof marker is compatible with a wide range of surfaces including wood, metal, glass, and colloid materials. The waterproof ink ensures your marks remain clear and durable even on smooth or porous surfaces.
Q: How many tips does this marker have, and what sizes are available?
A: This is a double-headed marker featuring two tip sizes — 0.7mm and 0.5mm — so you can switch between slightly broader lines and ultra-fine precision marks depending on your project requirements.
Q: Can I buy these markers in bulk?
A: Yes! This marker is available as a single pen (1PCS) or in convenient multipacks of 3, 5, or 10 pens in Black, Blue, or Red, as well as a mixed set of 2 Black + 2 Blue + 2 Red — ideal for workshops, classrooms, or professional use.
