After measuring and leveling the brackets, he needed to mark the exact drill points inside the pre-drilled holes. His regular pencil could not reach the bottom of the 20mm deep holes, and the marks kept smudging on the tile backsplash. He switched to this long nib marker, inserted the tip into each hole, and made a clean dot on the wall. The ink dried in seconds and stayed visible even when he wiped away dust. He finished the job in half the time with no re-drilling.\u003c\/p\u003e\n\u003cp\u003eMicro Comparison\u003c\/p\u003e\u003cp\u003eStandard markers with short nibs cannot reach deep into holes or recessed areas, forcing you to guess or measure twice. This set solves that problem with a 20mm long nib that marks exactly where you need it. The waterproof, fast-drying ink also outperforms pencils and washable markers, especially in bathrooms, basements, and outdoor workshops where moisture is a concern.\u003c\/p\u003e\n\u003cp\u003eSpecifications\u003c\/p\u003e\u003cp\u003eMaterial: Plastic\u003c\/p\u003e\n\u003cp\u003eHead Tip Length: 20mm \/ 0.8 in\u003c\/p\u003e\n\u003cp\u003eLine Width: 0.7-1.0mm \/ 0.03-0.04 in\u003c\/p\u003e\n\u003cp\u003eColors: Black, Blue, Red, Green, White\u003c\/p\u003e\n\u003cp\u003eInk Type: Waterproof, Fast Drying, Xylene-Free\u003c\/p\u003e\n\u003cp\u003eApplication: Woodworking, Metal Processing, Automotive, Furniture Decoration, Bathroom\u003c\/p\u003e\n\u003cp\u003ePlease allow 1-3 cm \/ 0.4-1.2 in difference due to manual measurement.
