## Long description

The uni-ball Chalk marker set TRADI, 4-piece assorted colors, round tip, stroke 1.8–2.5 mm is a set of liquid chalk markers created for temporary writing and drawing on non-porous surfaces. Each marker features a round tip that produces a consistent stroke between 1.8 and 2.5 mm, making the set suitable for medium-width lettering, signage and decorative artwork on chalkboards, glass, mirrors and other smooth surfaces. The ink is formulated to be removable with a damp cloth, allowing frequent updates to displays and seasonal designs.
Advantages
The markers deliver uniform color laydown and a predictable line width thanks to the round tip and the specified stroke range. The liquid chalk ink provides opaque coverage on dark backgrounds and good visibility on glass and mirrors. Removal with a damp cloth reduces the need for special cleaners and supports quick changes to messages or decorations. The four-colour assortment covers basic needs for contrasting and accenting text or illustrations.
Suitable for
Writing menus, prices and promotions on non-porous chalkboards
Decorative window displays and seasonal signage on glass
Temporary markings and labels on mirrors and whiteboards (non-permanent)
Craft projects that require removable color on smooth surfaces
When it may not be suitable
This marker set is intended for use on non-porous surfaces only; it is not formulated for porous materials such as paper, untreated wood, fabric or unsealed stone, where ink may soak in and not be removable. For permanent applications or outdoor long-term exposure, these markers are not appropriate because the ink is designed to be removable and may be affected by rain or abrasion.
Key specifications
Tip shape: round
Stroke width: 1.8–2.5 mm
Ink type: liquid chalk, opaque
Number of markers: 4 assorted colors
Removability: cleans off smooth non-porous surfaces with a damp cloth
How to use
Shake each marker well before use to mix the pigment. Depress the tip gently on a test surface until ink flows, then write or draw with steady pressure to maintain an even stroke. For best results on chalkboards and glass, ensure the surface is clean and dry before applying ink. To remove, wipe with a damp cloth; for stubborn residues, use mild detergent and a soft cloth. Store markers horizontally when not in use to maintain tip saturation.
What to consider before purchase
Intended surface: suitable only for non-porous surfaces such as glass, mirrors and sealed chalkboards
 permanence: ink is removable and not suitable for permanent markings
Stroke width: 1.8–2.5 mm is medium width—ensure this fits your lettering or artwork needs
Colour assortment: four colours provide basic contrast but may not replace a wider palette
Usage recommendations
For clear, consistent results, clean the writing surface before use, test each colour on a small area, and store the markers horizontally. Replace the cap after use to prevent the tips from drying out.
