Business owners and office managers, these PATIKIL push/pull door signs are such a simple but effective solution for preventing those awkward door confusion moments! The 3-pack gives you plenty for multiple entrances or to keep as spares. Made from durable 2mm thick acrylic with a sleek silver finish that looks professional on any glass door. The 3x3 inch size is perfect - large enough to be easily visible but not so big that it looks obtrusive. The adhesive backing is seriously strong - once you stick these on clean glass, they're not going anywhere, but they can be removed if needed without leaving residue. I installed these in our office building and they've completely eliminated people pushing on pull doors and vice versa. The installation is foolproof - just clean the glass surface, peel the backing, and press firmly. They also include transfer film for even easier application if you want that extra protection during installation. These are perfect for retail stores, restaurants, offices, hospitals - anywhere you have glass doors that need clear direction. The professional appearance makes your business look more put-together, and they actually work to improve traffic flow through doorways. After six months of constant use, they still look brand new - no fading, peeling, or discoloration. Such a simple investment that makes a big difference in customer experience and prevents wear and tear on your doors from people using them incorrectly.
