DIY Stapler Nailer - 1000 Nails and Staples Included

I bought this stapler for my sofa fabric 🛋. I received the protective plastic box opened all over the place ! In the picture you can see the stapler with an iron rectangle to hang it, I don't have it .! I tried on my wall, my sofa and on a wooden board it doesn't work . I'll get back to you as soon as I can get it working. !? . Otherwise despite the packaging, I found it great at the time and especially 3 types of staples very important 👍. Super fast delivery from France to France really great. Now the question is whether it works. ! ... I'll tell you as soon as possible. Thank you.
