1. The label is not tightly attached, and there will never be bubbles in the real goods, but now there are too many counterfeits, so it is difficult to distinguish them only from the packaging.

2. Look at the bottle mouth. Because the blending is upside down, there will be traces of soy sauce soup on the bottle mouth. And the little white cover in the middle. If it's a fake, the lid will easily dislocate and the plump one will come out.

3. Smell it, the real goods have the delicious taste of seafood, and the fake goods are blended with soy sauce and water, which tastes like raw soy sauce and tastes very heavy.

4. Color, the real goods are light in color and the fake goods are dark in color.

If you still can't tell the difference, you should send a text message to check the anti-counterfeiting, and the anti-counterfeiting coating is attached to the bottle mouth.
