How to install the sticker/patch
When using with a seal.
The sticker will not stick to wet or damp items.
Also, the surface may peel off when removing from paper or leather products.
If you leave it on for a long time, the adhesive may adhere to your clothes, etc.
Adhesive will wear out and will not remain permanent.
When using with an iron attachment.
Please use a hard ironing board and prepare a cloth with a brush.
1. Place patch on the desired area.
2. Set the iron temperature to dry medium temperature and make sure to apply a cloth and press firmly for about 20 to 30 seconds. (Wait until it completely cools down)
3. Iron on the back to ensure proper adhesion. (Wait until it completely cools down)
*If you have a bad stick, please try to recover it.
When attaching thick materials or attaching large objects, please apply a little bit of adhesive time and pressing force.
If you use it for a long time, attach it to items with a lot of washes, or if you want to attach it to a strong stick, please sew it.
