Large Cork Board, a traditional bulletin board alternative: Includes 12 felt wall tiles, each measuring 12” x 12” x 0.35”, 72 pieces of safely removable nano-adhesive, and 30 thumbtacks that won't penetrate the board, protecting the wall and ensuring safe use. High-quality environmentally friendly materials: Made of environmentally friendly polyester, it is safe, odorless, lightweight, high-density, and not easily deformed, giving you peace of mind when using it. Wide range of applications: Cork boards for offices are used to record important to-do items; in schools, they are used as poster boards, bulletin boards, family photo walls, and personal vision boards; thickened cork boards can also be used as dartboards to protect walls. Sound insulation performance: Large-area felt panels can effectively reduce echoes and noise, and can be used as sound-absorbing panels to create an ideal acoustic environment for home offices, schools, and recording studios, while also protecting walls from wear and tear. Easy and non-destructive installation: No drilling is required, making installation quick and convenient. Its strong nano-adhesive effectively prevents cork boards from falling off; and the adhesive can be safely removed without leaving any residue or damaging the wall surface. Cork Board
