Really good product.

This product used to whiten teeth and worked instantly. After just one use, I could see a significant difference.I bought this instead of strips because I wanted to address my molars. After one use, the difference was remarkable. While it may not be “perfect,” I’m confident that I’ll continue to see results with more uses.I highly recommend this product for anyone looking to whiten their teeth quickly, painlessly, and affordably.

meets all my needs for activated charcoal

As others have noted, the powder is EXTREMELY FINE. It will come flying out of the package when you open it, and it will get all over things. This is an inconvenience, but doesn't detract from the quality of the product; in fact, it's critical to the quality. If I'm going to be brushing my teeth with charcoal, I want it to be very fine. It's barely gritty at all.But the packaging, though I'm sure it keeps costs and shipping down, IS inconvenient. So here are a couple of tips: When you receive the package, stand it up and shake the product down. Let it settle for a good long while. Assemble two pint-size jars with lids (for the 8 ounce bag of charcoal).Carefully cut the top of the bag open (there's no way you're going to keep dipping into this bag of flying black powder, so sacrifice the bag). On an easy-wipe surface, decant the charcoal powder slowly and carefully into the two jars. I used a wide-mouth funnel.Close the jars up. It's much easier and neater to dip your toothbrush into a wide-mouth jar than into this bag.Some powder will scatter. Wipe it up with a microfiber cloth and some grease-cutting spray like Windex or 409.When you brush your teeth with this EXTREMELY FINE blacker-than-black powder, you will get black tongue and black gums. Mere water-rinsing doesn't make it go away. So I've been pre-brushing with the charcoal, then re-brushing with toothpaste or baking soda, which helps carry away the charcoal.I've read that charcoal shouldn't be used every day on teeth, so this is a once-a-week thing for me, and really not much trouble. I get a nice fresh mouth (I'm on a Very Low Carb diet and get "keto-breath") and super clean teeth. This 8 ounce bag of charcoal will last for years.

The seller delivered on time. The product works well. I highly recommend this product and seller.
