One look: how to look?

Let's take the bicycle helmet in our hand and carefully observe the holes in the helmet and the edge of the helmet. You can easily find fake one-piece bicycle helmets because of the level of craftsmanship. These places are small. Void, almost every hole has this phenomenon. This is not the case for bicycle helmets that are really one-piece. Because it injects EPS directly into the cap shell, just like we pour concrete beams, there is no gap between the formwork and the concrete, which is a perfect combination.

Second touch: How to touch, where to touch?

Or touch the places we just mentioned, just use our most sensitive fingers to touch these places up and down, left and right, you will feel that the fake one-piece bicycle helmet will be very scratchy, because it is not well integrated and there are gaps. The one-piece bicycle helmet is perfectly integrated without any gaps, so it will naturally not scratch our hands.

Three listens: How do I listen?

Just use one of our hands to hold the bicycle helmet, and the other hand to hit various places of the bicycle helmet. At this time, you will hear the sound like the sound that our things are empty or are about to break. But there is no broken sound, the sound is not clear, but muddy, then this bicycle helmet must be fake one-piece molding. And the sound of the real one-piece bicycle helmet is just like the sound of the solid wood furniture in our house.
