Japanese Hair Experiment: Soft Curls

Hey guys, I thought I'll vlog this hair experiment for you guys. It's not a hair tutorial. Just a product I came across and wanted to try out. I picked it up from my local Sasa store. It's a Japanese product called Goo Set. Cost about hk$108. That's over US$15 right? A little pricey. It's different from other hair styling products so I wanted to give it a test. I wouldn't say this is a MUST-HAVE product. It's quicker to just use a curling iron. Probably rate it 2 out of 5. I've tried sleeping with these on. They aren't too bad to sleep with but the curls didn't last very long either. Kind of like a gimmick product. Not really worth it. You guys tried it before?
