New four hole CBD cartridge

If you have ever bought a CBD cartridge, you may ask yourself "What are the small holes inside the filter element?" Well, don't worry, because you are not alone. It turns out that most users do not know the purpose of these vulnerabilities. Their size and number vary by cartridge type. If you are like most of us, you might just shrug your shoulders and continue your day's work, filling your cartridge with oil, and then vape it out. But these holes are actually one of the most important aspects of the cartridge. They can determine the resistance and taste of the product when the product is inhaled.

When determining the proper size of the oil inlet hole, the typical rule followed by our Yarktech company is very simple: "The thicker the oil, the larger the hole". For example, the capacity of the glass cartridge we carry is 0.5 ML to 1.0 ML. If the consistency of the oil to be filled with oil is very thin, it is better to use a smaller oil inlet size. However, if the consistency of the oil is really thick, then you may need our larger oil inlet hole, but in order to prevent the complexity of customization and the instability of customer testing, we have added this full ceramic with 4 oil inlet holes CBD cartridges are specially designed to deal with high-concentration oil CBD and THC cartridges, reducing the complicated process of testing cartridges for customers and greatly increasing the versatility.
