To provide a label with parallel perforated lines by which a residual quantity of contents in a bottled product can be always known without opening its cap and looking into the inside of the bottle.

Perforated lines 1 and 2 are vertically made in parallel in the middle part of a label, and a slit part 3 is secured between both the perforated lines. When using it, the slit part 3 of the label affixed on a bottle is pulled from the upper end or the lower end to be peeled off. As a result, the inside of the bottle, which is covered with the label, can be seen through the slit. The label main bodies 1, (4) and the label main bodies 2, (5) are left as they are.
