Elementary school class. Stainless steel cup drawing

How can you express the glittering feeling of a stainless steel cup? Everyone thinks from the hint. One of the hints "If it stays white, it won't shine even if you try to make it shine." The shape of the handle was so hard that I couldn't figure out where it was drawn, but I looked closely and touched it to overcome it! All the glittering stainless steel cups are complete! Everyone did their best!
