Edding 850 Permanent Marker Block Blue

The Edding 850 Block Blue permanent marker offers bold blue ink and a block tip designed for strong, consistent lines across many surfaces. This set of five markers provides a reliable option for tasks requiring visible, waterproof, and lightfast markings. The marker’s ink is formulated to resist fading and moisture, suitable for both indoor and outdoor applications where durable, clear labeling is needed.

Advantages

The block tip creates uniform, saturated strokes that remain legible over time. Waterproof and lightfast ink minimizes smearing and color loss, while the casing and cap are designed for comfortable handling and secure storage. Pack quantity of five ensures a steady supply for repeated or multi-location tasks, reducing the need for frequent replacement.

Suitable for

• Labeling containers, boxes and equipment

• Crafting and DIY projects requiring vivid blue lines
• Office use for files, folders and inventory marking

How to use

Shake the marker gently before use to ensure even ink flow. Remove the cap and press the block tip briefly onto a test surface to start the ink flow if necessary. Apply consistent pressure for uniform lines; turn the marker to use different edges of the block tip for varied stroke widths. Replace the cap securely after use to prevent drying and store horizontally or upright with the cap on.

Recommendations

For best long-term visibility, test on a small area of the intended surface to confirm adhesion and color fidelity. Avoid using on untreated textile or highly porous surfaces for permanent results. When marking on glass or metal, allow extra drying time to ensure the ink has fully adhered.
