the button above the toilet is where you push to flush the toilet. i always see either this type or the one where you pull the string. by the way you CANNOT flush toilet paper/anything other than your own waste down these toilets because the plumbing tubes are too thin for that stuff . so throw everything away in the trash can.
canudos! these are the only type of straws i've seen around here. they're pretty long and thin. they always give me one of these when i buy a côco. mmmmmm..
