Save the ketchup! / ketchup bottle for perfect use

There is a memory in which my mother gave me a fried food with a little remained ketchup after cutting the container’s bottom so as to use it frugally and conveniently. This idea was arisen from the wisdom of my mother who has practiced frugality. Moreover, switching applications are possible by
separating the container’s upper part easily without
using additional tools such as scissors, and also
this part can become a clean spice plate because
the figure after cutting it does not display tough
scissors marks.
