I see this is an older post but I want to add that I use a container like that and I blue tape the package of the needle I have in the machine, on to the container top. I change thread and quilt on painted fabrics often which sometimes requires a change in needle and I can quickly see what size/which needle is in the machine. If it is a project with days of quilting I may write the date on the tape too so I'll know when the needle was new.
