I purchased this as a spare, but it seems I won't need it, so I'm offering it for sale while it's still new. I used it once to test if the LED glue would harden. Like the Laser Lash Pro, it's a tweezer-insert type. This product was exhibited at Beautyworld. This is currently the most popular LED light for eyelash extensions overseas, and it's cordless. The battery can be used continuously for two hours without stopping. In the salon, I was able to treat 4 customers. You can also use it while charging, so there's no problem with business even if the battery runs out. The light body is made of soft silicone, so I think it can be used for almost anything.
