Permanent Marker Set LEANToys — 10 black waterproof markers, fine/medium tips

LEANToys permanent marker set includes 10 black waterproof markers designed for durable marking on a variety of surfaces. The markers deliver consistent, highly pigmented black ink that is resistant to smudging and light fading, suitable for office, school, workshop and home environments where long-lasting legibility is important.

Advantages

The set combines fine and medium tips to provide both precise lines and broader strokes with a single product range. Waterproof, quick-drying ink reduces the risk of smearing after application and adheres well to paper, cardboard and many plastics. Ergonomic barrel design supports comfortable handling during repetitive marking tasks, and a cap with a secure closure helps preserve ink between uses.

• Labeling files, boxes and storage containers

• Marking tools, plastic parts and equipment
• School projects, arts and crafts that require permanent ink

How to use

Shake the marker briefly before use to ensure even ink flow. Remove the cap and apply the tip to the surface with light, steady pressure for fine lines or increased pressure for broader strokes. Allow the ink to dry for a few seconds to minimize contact smudging. Replace the cap securely after use to prevent the tip from drying out.

Usage recommendations

For best results, test the marker on an inconspicuous area of the material first to confirm adhesion and drying time. Avoid use on highly absorbent surfaces if a crisp line is required, and store markers horizontally or with the cap on to maintain consistent ink flow.
