I recommend this cans as gifts for adults instead of children because when you pull the tap to open the can, it is going to leave sharp edges, so children could cut their fingers. However, for adults is a very clever idea. If you want to use the can again then I recommend to use a can opener that takes all the seal off so you could use the can as pencil holder or such.
