1, prepare the seal first, and pay attention to the structure clearly, otherwise the plastic buckle will break easily.

2. Open the outermost cover first (that is, it is usually opened when stamping).

As shown in the figure, when you see two buttons (one on each side), press them in with two fingers, and then pull them out in the direction of the arrow.

4. Expose the back of the seal.

5. Shake the photosensitive ink in your hand a few times.

6. Squeeze the ink into the back of the seal.

7. Never refuel according to the method shown below. Because the excess fish oil is usually wiped after adding oil in this way, the coating on the surface may be wiped off after a long time.
