Pennarello Sigel GL715 punta bullet bianco

The Sigel GL715 Bullet tip White marker writes in opaque white ink designed specifically for use on dark or coloured glass surfaces. Its grey barrel houses a ready-to-use nib that delivers consistent white lines without pumping, making it suitable for office glass boards, mirrors, window panes and other sealed surfaces where high contrast is required.

Advantages

White ink provides strong contrast on dark or coloured glass and dries quickly. The marker requires no pumping — the ink flows immediately for uninterrupted writing. Its bullet tip produces controlled, even lines and the product is compatible with most sealed surfaces, offering flexible indoor use.

Suitable for

• Black or coloured glass boards in offices and meeting rooms
• Writing messages on mirrors and window panes at home
• Craft projects on sealed dark glass surfaces

How to use

Shake the marker gently before use if recommended by the manufacturer, then remove the cap and write directly on the sealed glass surface. The ink flows instantly without the need to pump the nib; apply light, even pressure for consistent lines. Allow the ink to dry before touching the surface to avoid smudging. Clean marks from glass with appropriate glass cleaner or a damp cloth when needed.

Recommendations

To prolong marker life, store it flat or upright in a desk organiser with the cap pointing downward; avoid exposure to extreme temperatures and always replace the cap after use to prevent the tip from drying out.
