Cheap metal and plastic of a different color

The rings are good and beautiful, but the plastic one is not adjustable and is for thick fingers. I have a medium size 16-16.5 and it's huge, and it also falls off my thumb. So what can I do with it? Just admire it... but the silver one is adjustable and looks beautiful.

The metal ring matches the photo perfectly, while the plastic one is more brownish in color and has a softer tone. They arrived without any defects.
