## Long description

Edding BTK-25 blue 25 ml is a refill ink bottle for compatible Edding marker housings. The refill contains 25 ml of blue ink formulated for marker and whiteboard use, supplied in a compact bottle with a capillary refill system. The refill restores writing performance of permanent and whiteboard markers by allowing the pen tip to draw ink directly from the bottle when placed nib-down for at least an hour. The product is made in Germany and sold as a single refill bottle.
Advantages
The capillary refill system enables controlled, low-mess refilling of compatible markers and supports quick and straightforward restoration of ink supply without disassembling the pen. The 25 ml volume provides multiple refills for many marker types, reducing the need to replace entire pens and thus lowering waste and long-term costs. The formula is designed for low odour and quick drying, delivering consistent writing performance and good lightfastness for everyday use.
Suitable for
Replenishing compatible Edding whiteboard and marker pens

How to use
To refill a marker, remove any protective cap from the marker nib and place the marker nib-down into the refill bottle so the tip is submerged. Leave the marker in the bottle for at least one hour or ideally overnight to allow ink to be drawn into the nib by the capillary system. After refilling, remove the marker, wipe any excess ink from the nib or housing if necessary, replace the marker cap and test on a suitable surface. Store the refill bottle upright with the cap closed when not in use.
Usage recommendations
Use the refill with markers indicated as compatible by the manufacturer. Work on a protected surface and avoid skin contact with ink; clean spills promptly. For best results, leave the marker in the bottle overnight if the marker was fully dry. Keep the bottle tightly closed and store at normal room temperature away from direct sunlight.
