Absolutely brilliant customer service and prices. They helped me to pick all the accessories for my vape and perfectly described santa cruz jumbo grinder, that a.t.m. has the best price in the world. The grinder can hold up to half an ounce of herb! It's perfect for concentrates, edibles, or tinctures, when you need a lot of ground material at once. No grinder I had ground so much herb so quickly. There is a lot of usable space for grinding, without the fear of smashing your herb in the center or around the edges, yet the teeth aren't spaced too far apart. This means you can use this thing with small amounts as well! Because of it's size it twists so easy my grandma could use it. Fast and discreet delivery as well. My favorite web store in the U.K!
