Hi, we meet again. What I recommend to you today is the A4 sign holder. This non-marking reusable A4 sign holder can easily replace all kinds of posters, reused more than 1000 times without leaving any marks, always keep it clean and tidy. Best of all, the double-sided tape can be rinsed with clean water and used like new after it dries. Has a wider range of application scenarios, used on clean and flat surfaces, such as marble, glass, plastic, wood, metal, leather, etc...
