Most of the candle tumblers are made of high-temperature silicon. They are made of high boron heat-resistant glass, which has good heat resistance and corrosion resistance. As a green and environmentally friendly glass material, the cup body is crystal clear, with a smooth feel and elegant shape. The following points should be noted for the candle tumblers wholesale:
- The material should be pure: the glass material is not pure, and there will be lines, bubbles or sand.
- The thickness shall be consistent: that is, the glass materials at all parts of the cup shall be evenly distributed. When selecting, the user will observe the cup against the light. If the light perception is consistent and integrated, it means that the thickness is consistent; If the difference between light and shade is too large, the thickness is inconsistent. When selecting, from the outside, the bottom should be horizontal, not slope or pot bottom. Flick the walls with your fingers to make a pleasant sound.
- The appearance shall be beautiful: the surface shall be smooth, the gloss shall be good, the geometric shape shall be flat, and the cover shall not be too loose or too tight.
