I have tested your Mega Volume tweezer, and unfortunately I'm very disappointed with its performance.
Although it is marketed as a Mega Volume tweezer, it struggles to grip lash fans properly. The lashes frequently slip out, making it difficult to pick up larger fans. In fact, even when picking up only 4–5 lashes, the tweezer tends to slip and causes the fan to become misaligned.
I do like the light tension of the tweezer, as it feels comfortable to use. However, this benefit is outweighed by the fact that the tip cannot securely grip multiple lashes, which is a basic expectation for a tweezer advertised as a Mega Volume tweezer.
Based on my experience, the product does not perform as described, and I would appreciate your feedback regarding this issue.
