Are these water and oil proof ? I need to be able to write on a grain of rice .

probably wouldn’t be successful

will these pens smear with highlighter?

No is just reguler pen but I didn't suggest you buy this pen. Because they will spend about 2month shipping from Japan

How long doeg is the shipping to Mexico?

Hi!it would take 10-15days to mexico from japan.thanks!

Does it bleed to the other side of the paper?

No. If you are writing normally it doesnt bleed. It does if you hold the pen at the same place for a bit or if you write in the same place over and over.
