Ideal Use

• Laboratory and Medical: Ideal for healthcare professionals to label test tubes, slides, and sample bags where space is limited.
• Electronic Component Marking: Perfect for technicians needing to mark small wires, circuit boards, or hardware during assembly and repair.
• Office Organisation: Use it for detailed labelling of file tabs, CD/DVD surfaces, and small plastic storage bins.
• Industrial Identification: Excellent for marking small metal parts, tools, or keys with permanent, legible identification codes.

Safety and Maintenance

• Cap Security: Ensure the cap clicks firmly into place to maintain the integrity of the fine nib and prevent evaporation.
• Surface Preparation: For the most permanent results on glass or metal, ensure the surface is free of oil and dust before marking.
• Storage: Store horizontally to ensure consistent ink flow to the fine tip, especially in the warm climate.
• Removal: If a mistake is made on a non-porous surface like glass, the ink can often be removed using a small amount of alcohol-based cleaner.

Frequently Asked Questions

• Is the ink really permanent? Yes, the ink is designed to be waterproof and highly resistant to rubbing once fully dried on most surfaces.
• Can I use it on glossy photos? Absolutely; the instant-dry formula is perfect for writing on the back of photographs without the risk of ink transfer.
• Will the tip dry out if the cap is left off? While it is designed for durability, always replace the cap after use to ensure the ultra-fine 0.4mm tip remains moist and ready for use.
• Does it bleed through paper? Like most permanent markers, some show-through may occur on thin paper, but it is ideal for heavy card and non-porous materials.

The "Micro-Labelling" Pro Tip

• When you need to label very small items, such as the heads of screws or small cable ties for a home theatre setup, use the Artline EK725 to write directly onto a piece of clear adhesive tape before sticking it down.
• This allows the ultra-fine 0.4mm ink to settle perfectly on the tape, providing a professional and permanent label that won't smudge or fade even with frequent handling.
