Blue Glue Pen by Penco is both practical and cute that can be used for different purposes.
It is acid free and xylene free which prevents paper from changing its colour or being wrinkled.
Before drying, the glue shows a blue colour with very strong adhesive properties, guiding you to stick on sharply and clearly. After drying, the glue will become transparent with weaker adhesive properties, where you can stick on or peel off easily for a more casual use.
