Süstlapliiatsid

Süstlapliiatsid are a type of writing instrument that combine the functionality of a pencil with the convenience of a pen. Essentially, they utilize a graphite core, similar to a traditional pencil, but encased in a mechanism that allows for retraction and extension, much like a retractable ballpoint pen. This design eliminates the need for sharpening, as the graphite lead is advanced by twisting or clicking a button.

The graphite used in süstlapliiatsid is typically a refined graphite powder mixed with a binder. This allows for a consistent line and varying degrees of hardness, often indicated by numbers and letters on the casing, similar to standard pencils. The tip of the süstlapliiats is usually made of metal or durable plastic, providing support for the lead and a smooth writing experience.

These writing tools are popular for their practicality and cleanliness. They do not produce the dust associated with traditional pencil sharpening, making them ideal for use on the go or in environments where mess is a concern. Süstlapliiatsid are widely used by students, artists, and professionals for everyday writing, sketching, and note-taking. They offer the erasability of a pencil with the portability and ease of use of a pen.
