Daiso Gua Sha, is this what "happiness for 1,000 won" means?

I saw a recommendation for Gua Sha massage on YouTube, but since expensive products were a bit of a burden, I bought a 1,000-won one from Daiso. However, it turned out to be quite good. Before bed, I applied a generous amount of moisturizer and rubbed from my chin to behind my ears; at first, it hurt surprisingly much. I think my jaw muscles were severely knotted due to my habit of clenching my teeth. But I endured it and kept loosening the muscles, and it started to feel refreshing. After repeating this for a few days, my morning swelling definitely decreased. If I also massaged my neck, shoulders, and trapezius muscles, it relieved the day's fatigue and helped me sleep better at night. You don't necessarily need expensive tools to do this. Above all, I think consistency is the most important thing. Isn't this the best value for money for just 1,000 won? It's small enough to fit perfectly in a pouch, so I plan to take it with me when I travel. If you are worried about swelling, you have nothing to lose, so go to Daiso right now and give it a try.
