Ok for the price but not amazing
Flavor Name: Ceremonial Grade, Size: 1.4 oz (40g)
It is fine for the price but has a bit of that unpleasant cheap matcha taste so wont be rebuying. Decent bitterness but not really creamy or sweet in my opinion. The color is good tho so aesthetically it is very pretty.

Best quality for price!
Flavor Name: Ceremonial Grade, Size: 1.4 oz (40g)
One of the best ceremonial matcha powders I’ve ever tried! It blends and froths up so easily and it tastes like true authentic matcha. I was very surprised with the quality and so happy I found a new one.

Cute matcha set, quality for price
Color: Pink, Color: Pink
I was looking for an affordable, quick replacement for my previous matcha set and found this item. For the price point, this is great quality and is such a cute addition to my kitchen. I also like that this includes all the essentials for making a matcha. The chasen does seem to be on the more fragile side though so I'd just be careful and properly take care of it such as blooming it in hot water before any usage and whisk with a very lighthand.

Cute!
Color: Green
Super cute and fun to use, easy to clean, appears to be very well-made. Excellent, especially for such a low price. I will say the only complaint I have is that the spout design could use some work; the end of it doesn't come out far enough so it dribbles a bit when you try to pour. Also, and maybe this is to be expected due to the use of natural materials, but there are a couple of small split pieces/splinters on the chasen (whisk) I had to trim. Otherwise perfect!
