Yellow Office Thumbtacks, in a box of 100 units, are small, wide-headed thumbtacks used to attach papers, posters, or notices to cork boards and soft surfaces. The wide head facilitates handling and removal without damaging the attached paper, and the box of 100 units ensures autonomy for prolonged use in offices or classrooms. The yellow color facilitates visual organization when using several shades simultaneously, for example, to code different categories on a notice board. It is a preferred option for offices, schools, and workspaces that need to attach documents quickly and reusably.
