FAQ: SunKnob LED Door Knobs
Material & Craft
Our product line comprises two premium collections: Artistic Resin Handles and Luxury Crystal Handles. All models feature solid brass as their base hardware. The resin models encapsulate 100% authentic artistic scenes, sealed within a highly transparent resin medium; the crystal handles, conversely, are crafted from high-hardness, transparent crystal material and are designed in a diverse array of shapes and styles.
A: Yes. We use real preserved hydrangeas, dandelions and natural specimens, professionally sealed in UV-resistant resin to lock in their original delicate beauty permanently.
A: The crystal handle features a pure, translucent, and polished crystal material, perfectly complementing modern minimalist, "light luxury," and Nordic-style aesthetics. The artistic resin handle, conversely, encases real preserved flowers and whimsical scenes, making it an ideal choice for Bohemian, rustic cottage, and artistically inspired home decor. Both handle models support a seven-color (including the original color) shifting LED lighting effect and feature a wireless, battery-powered design..

Traditional Method: The circular base is attached using strong adhesive; consequently, its load-bearing capacity relies entirely on the strength of the glue. With prolonged use—or if the manufacturer utilizes inferior adhesive—the knob is highly prone to slipping or detaching.
Our Method: We have redesigned the circular base into a hexagonal shape, which is then secured with strong adhesive. This design ensures that the knob remains firmly attached even after extended use, as the structural load is borne by the knob itself rather than by the adhesive.
