I have never heard of powdered wasabi before. I was interested to see if it was hotter than the kind out of a tube or homemade. It's pretty okay compared to that. It wasn't bad. I could make it last longer. Price wasn't bad either.
I started using Sonia Kashuk because I found her stuff on sale at Target and now it's defintiely worth paying full price for. Her stuff is dependable and at a good price. I use her brushes a lot. They lasted very long. I was defintiely satisfied. I recommend the product.
