螺旋针 / A Curved Needle

螺旋针
螺旋针

Compared with the old products, our products have some significantly excellent features:
It is easy to pick it up whenever we want to use.
When we want to sew clothes, we have to pinch the middle of the needle with power in order to increase the friction, which can be so inconvenient. However, our products just pinch the bended place with a little power, which is much more labor-saving, compared with the old ones.
