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.
When painting a wide area, use the surface
When painting small parts, use the corners
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.
You can evenly apply to the corners of the lid
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.
