Thank you for viewing. Regarding the lighting of the penlight, I have not been able to confirm it as it is unopened. I don't think there will be any issues, but if there are any defects, please contact the manufacturer directly. Regarding 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 is only amateur packaging.
