GUESS WHAT I AM!

I am tall and thin, but I can be all different shapes and sizes. I am very fragile, so don’t hurt me because I break easily. Some people say I am half empty, some say I am half full. I am hollow on the inside, unless I am in use. You can see right through me. I can have stripes, dots, zigzags, swirls, animals, or anything you can think of covering me. My colors vary from red, blue, orange, or any color in the rainbow. I can be very expensive or I can cheap depending on what you want out of me. Some people love me, some people hate me. I guess its preference. I don’t really like little kids around me, they are too rough.  Sometimes I can look dingy, but most of the time I sparkle in the light. Take a try and see if you can guess what I am??
