Feature:

This set of suction cups has 4 specifications, and a suction pen has 4 suction heads.
The greater the suction, the stronger. A suction cup with a large diameter only needs to suck a lens with a large diameter.
The lens with a small diameter and a large arc, the larger the diameter, the stronger the suction, but the higher the curvature of the mirror, the smaller the diameter, the more large the lens can be absorbed, but the suction is slightly weaker . Except for extreme lenses, it can basically be used.

Instructions:
When there is a lens that is not easy to take out, use this suction cup to gently pinch the penholder to exhaust the air, then stick it on the surface of the lens, lift the lens out, and then slowly put it in a suitable place.,

Special Note:
The larger the suction cup, the stronger the suction. In principle, you should try to use a larger suction cup, but when you encounter a lens with a large curvature, you can only choose a small one. Please handle it gently during the suction process. Make sure to suck it up and then lift it out. The lens will fall in the middle. We are not responsible for damage caused by falling.
