As for this specific matcha product, it comes in a sealed bag and is very secure. The matcha is culinary grade, which isn’t the highest (ceremonial is the highest) but it is still high quality and great to have mixed in dishes! I’ve used matcha before to make matcha bread that was actually pretty good! As I mentioned earlier, I also put matcha in my smoothies to make them even healthier! Overall, this is a really nice matcha that you can use to add color or health benefits to your dishes and is a great thing to add to your life!
