1. Check the Material
High-quality carbon crystal wall panels have a smooth surface, no obvious scratches, a delicate feel, and no odor. Inquire about environmental certifications before purchasing.
2. Check the Brand
Choose well-known brands such as Oppein, TBB, and Qiannianzhou to ensure reliable quality and after-sales service.
3. Check the Jointing Effect
High-quality carbon crystal wall panels have small gaps between joints, a strong overall appearance, and are less prone to loosening or falling off after installation.
