Chalk sticks Astra Jumbo Fun, pack of 5 — Astra model 560218

Astra Jumbo Fun chalk sticks, pack of 5, are oversized white chalks designed for writing and drawing on blackboards, chalkboards, and similar matte surfaces. Each stick is thicker than standard school chalk to provide a comfortable grip and produce bold, highly visible lines. The set is intended for classroom use, workshops, presentations, and recreational art activities where easy handling and clear visibility are required.

Advantages

The jumbo diameter of these chalk sticks improves control and reduces hand fatigue during extended use, making them suitable for both adults and children. Their dense composition produces consistent, opaque marks that remain visible from a distance. The larger size reduces the frequency of replacement and is less likely to break during normal handling compared with thinner chalk sticks.

Suitable for

• Classroom teaching on blackboards and chalkboards
• Workshops, seminars and presentations requiring clear legibility
• Children's drawing and craft activities on matte surfaces
• Temporary signage on chalkboard-style menu boards and displays

Key specifications

How to use

Hold the jumbo chalk stick in a relaxed grip and apply gentle pressure to achieve even, continuous lines. For thicker or bolder strokes, increase pressure or rotate the stick to use more surface area. To erase, use a standard chalkboard eraser or a damp cloth for more thorough cleaning; allow the board to dry before writing again. Store the chalk in a dry place to prevent moisture absorption which can affect marking quality.

Usage recommendations

Use the Astra Jumbo Fun chalk for large-format writing and illustrations where visibility is important. Keep an eraser and a cleaning cloth nearby to maintain a clear surface. Avoid exposure to rain or high humidity to preserve the chalk's performance.
