Piirtopinnat

Piirtopinnat, also known as "drawing pins" or "thumbtacks," are small, sharp-pointed fasteners used to attach paper or other materials to a surface. They are typically made of metal and have a flat head with a hole in the center, allowing them to be easily pushed through the material and then pulled back to secure it. Piirtopinnat are commonly used in offices, schools, and homes for various purposes, such as hanging notes, posters, or other documents. They are available in different sizes and materials, including brass, stainless steel, and plastic. Piirtopinnat are a simple and convenient tool for temporary fastenings, but they should be used with care to avoid damaging the surface or the material being attached.
