Thank you for viewing. Regarding the penlight's illumination, I haven't been able to confirm it as it's unopened. I don't think there will be any issues, but if there are any defects, please contact the manufacturer directly. For packaging, I will use bubble wrap for simple packaging and ship it in a Takkyubin Compact cardboard box. *Please refrain from purchasing if you are sensitive about the packaging condition, as it will be done by an amateur.
