It's been 5 months since I got it and it's still there! I got the 1CC Neuramis and I thought the effect would be dramatic, but that wasn't the case and I just felt like I had a slight chin..? I paid 150,000 won for it, including the gravel ledge, but it was a waste of money. But I guess I'll get it again this vacation hahahaha. Looking at the previous photos, the ledge was just missing ㅠㅜ
