The letters need to be glued with super glue. I used chopsticks or just some kind of stick to put them in place. There is “inside stop” witch isn't necessary, but its keep the money part from opening easily. It need to be glued from the inside. Use stick also. The lid of the box needs to be glued. Place the lid AFTER you assembled everything. And lower stop needs to be glued on the bottom and in the back of the money holder to not let the money holder to fall out.
