Marker refill Edding RBTK 25, 25 ml blue ink, replacement for Edding markers

Edding RBTK 25 is a 25 ml blue marker refill intended to restore ink levels in compatible refillable Edding markers. The dye-based liquid ink is formulated for writing, labeling and drawing on paper and other porous surfaces. Supplied as a single refill bottle with a dispensing nozzle, the product is designed for controlled refilling to reduce waste compared with disposable markers and to extend the service life of refillable marker models.

Advantages

The dye-based formula provides consistent color flow and quick saturation on porous paper, producing clear lines and legible labels. A 25 ml volume supplies multiple refills for standard refillable markers, lowering long-term consumable costs. The refill bottle with dispensing nozzle enables measured application, helping to minimise spills and overfilling, and the blue ink is matched to the colour characteristics typically used in Edding blue marker ranges for uniform results across refills.

Suitable for

• Refilling compatible Edding refillable markers used for everyday writing and labelling
• Drawing, sketching and note-taking on porous paper surfaces
• Maintaining marker sets in offices, schools and workshops

Key specifications

• Ink type: dye-based liquid ink
• Colour: blue
• Volume: 25 ml
• Intended surfaces: paper and other porous surfaces
• Packaging: refill bottle with dispensing nozzle for controlled pouring

How to use

Confirm the marker is a compatible refillable Edding model and place it on a protected surface before refilling. Open the refill bottle and carefully apply small amounts of ink to the marker reservoir or directly to the nib following the marker manufacturer’s instructions. Allow the ink to distribute into the nib or reservoir and avoid overfilling. After refilling, close the bottle tightly and store it upright in a cool, dry place away from direct sunlight.

Usage recommendations

Wear protective gloves when handling larger quantities and keep the bottle out of reach of children. Test the ink on scrap paper if exact colour matching is required. Dispose of empty bottles in accordance with local waste disposal regulations.
