2 x Blue Light Penlight Pen Type Flashlight One Mode Blue Light LED Torch for Camping Hiking Fishing Hunting Animal Protecting Night Vision

I use it when quilting to be able to differentiate which is the right side of white on white fabric

Very bright, works great

I use this blue light to find the right side of white fabric. Plain and designed fabric

Small enough to carry in my purse and works like a charm.

the work great i m a sub arc base welder i use it for job to find flux.

The first time turning it on, it sparked and blew out the light. Also don’t confuse with a UV light. This is just a blue lightbulb. Does not work as a UV light pen.

Much brighter than expected. Compact but lights up the whole room. Packaged very well, fast shipping. Thank you so much!

Light is good
