Is this Jenny and Ji-soo?

Jenny, a fake intellectual show, has a good relationship. The brother I met last time said that they were good friends and went to the bathhouse together during their internship, so they really had a good relationship. BP has been practicing together for 6 years, not to mention only two Koreans, Jenny and jisoo, and they should have a good relationship.

Judging from the thickness of the ultraviolet panel

Generally, poor quality and cheap price are all due to insufficient thickness. The thickness of the 3MM UV panel is only 2.6-2.9MM, and that of the 5MM UV panel is only 4.6-4.9 mm.. The thinner the thickness, the cheaper the price and the worse the quality of UV panel.

2. Judging from the gloss of UV paint surface,

Generally, the poor quality UV board has a dark gloss, while the UV board made of real UV paint can achieve specular highlights, and people's shadows can be reflected from the surface of the UV board, which is similar to the effect of a mirror.

3. From the surface flatness of UV panel.

Generally, when the surface of a poor quality UV panel is facing the light, many large and small particles can be seen. The surface smoothness of real UV panels is generally better, and there are no big particles at all, but small particles a little bit the size of a needle tip. This is a normal phenomenon, because as far as the current UV panel technology is concerned, it can't be as flat as a mirror.

4. Distinguish from the smell of UV board

Generally, poor quality UV panels are not thick enough. His UV board substrate is inherently poor, and the formaldehyde content of UV board substrate is of course high. Besides, the paint used is not good. The made UV panels are smelly and will not come apart for a long time. Good UV board, good substrate, formaldehyde content in line with national standards, and good UV paint. When the UV board first comes out of the production line, it won't be scattered because of the heat, and it will taste a little, but after a while,
