Advice:
your choice of tweezers is subjective. If you’re comfortable with the tool you’re working with and get the result you want, there’s no need to change models, as you’ll be wasting time. On the contrary, if this isn’t the case, it may be a good idea to try out another model suited to your technique.
Cleaning:
It’s very important to disinfect your tweezers between each customer. For glue residues on your tweezers, simply soak for a few minutes in acetone.
