Easy to apply even small parts! Introducing the epoch-making glue stick "Delta Triangle Glue".
This product is a glue stick with a triangular surface to be painted. A wide area can be painted with a surface, and a small area can be painted with a corner.
It is possible to apply the lid of an envelope, etc. to the edge with a single coat and close it exactly. You don't have to worry about it sticking out of your desk. Since the main body is a triangular prism, it is also nice that it does not roll off the desk.
The purchase price at the stationery store is 150 yen (tax included). If you are a careful person who is worried about the sticking out of the glue and uneven coating, why not try it.
