Glass bottles are divided into wide-mouth bottles and narrow-mouth bottles. Solid paste is usually a wide-mouth bottle. It should come with an aluminum cap or a plastic cap. Caps can be used for colored sprays and other effects; lotion or water-based paste bodies usually use narrow-mouth bottles, which should be equipped with a pump head. If the cap is equipped with an inner stopper, the aqueous is equipped with a small hole and an inner stopper, and the thicker emulsions are equipped with a large-hole inner stopper.
Combinations：
1.cream bottle series: glass bottle body + double-layer plastic cap (general capacity of 10g-50g)
2.essence series: glass bottle + plastic pump head or anodized aluminum pump head (relatively high, 20 to 100ml)
