三菱鉛筆 Uni Highlighter Propus Window, 3 Color Set (PUS102T3C)

Is the packaging for these highlighters like the mildliners in that it's like a pencil box almost? Or is it a box you tear open and throw away?

Do these highlighters smear gel pen ink? How about ballpoint pen ink?

Are you able to see the text that you have highlighted?

If u xerox a highlighted page, does it show the highlighting show on the copied page?
