So now no need to buy luggage again and again. As you can see we can also call it explosion proof zipper. it is very difficult to break this zipper. This is very safe for travelers and tourists. i remember one time someone broke my zipper and take some important documents from my luggage,it was a very difficult time. but now no need to worry about safety of your luggage as you can see this zipper . I hope we can introduce this in market as soon as possible. so now travelers and tourists no need to worry about their luggage. This is very safe.
