My daughter is obsessed with matcha, so when I found this for Easter I knew it was the one. She makes her own latte every single morning, so this fit perfectly into her routine. The packaging alone is gorgeous — the colors worked beautifully with the Easter basket without me having to do much styling at all. Everything she needs to make her matcha was included in the box, nothing missing, nothing to track down separately. I was so happy I stumbled across this, and she absolutely loved it. Honestly one of those gifts that just lands exactly right.

Nice, but no spoon

Color: Green

It is a very nice set, but I was disappointed that I did not receive the spoon with the set.

Excellent matcha powder

Flavor Name: Ceremonial Grade, Size: 1.4 oz (40g)

The color is a vibrant, electric green right out of the tin, which let me know immediately that it’s actually a high-quality first harvest. It whisks up into a beautiful, silky froth with absolutely zero bitterness or chalky aftertaste. I’ve been drinking it straight with just hot water every morning, and it gives me a smooth, clean energy boost without the usual coffee jitters. Honestly, for a certified ceremonial grade, the quality you get for the price makes this an absolute staple in my kitchen now.
