Review (5/5): Works great, and shipping error speedily resolved by customer support
When I first received the product, the beard pen was missing! Only the tiny brush was present in the box.
I contacted their customer support about the incorrectly packaged product, and to my pleasant surprise, within half an hour they notified me that they had shipped out a replacement and provided me with a tracking number.
When it arrived, the beard pen was present this time. Now that's top-tier customer support!
The beard pen itself works great. It's very, very hard to even deliberately take off. It took lots of scrubbing before I was able to begin to wash it off my finger, so this thing certainly would last a day of use with sweat and rain without bleeding.
