Need a clear safety reminder for a door, cabinet, or machine? This TRUSCO sign does the job simply. It's a 150mm x 100mm (about 6\ x 4\) sticker that says \Keep Closed\ in both Japanese and English, making it useful in multilingual workplaces. The message is straightforward and important for safety or energy conservation. It's made from a durable PET film with an adhesive backing, so you can just peel and stick it onto any clean, smooth surface – no screws or tools needed. The materials are eco-friendly, using recycled plastics. It's a professional-looking, low-profile way to communicate an important instruction in factories, workshops, offices, or even at home on utility closet doors. The adhesive is strong, so it should stay put. A simple, effective solution for keeping areas secure and reminding people to close doors behind them.
