맨손으로 두 구멍 따먹기

I have nice long, healthy, strong that nails. I tap them on a wooden box. I try different camera angles as well for you to enjoy the sights and sounds of my nails tapping. Then I get curious on how different it would sound on the other side of the box (thicker wood), doesn't the sound send a tingle down your spine? In this clip: multiple camera angles,nails , fingers, drumming, ASMR
