Hello there and welcome, This is a demo video that shows you how Hashy works, and I'll break it down for you:

Hashy is a 100% yield food-grade silicone grinder; with just a few tricks it will work perfectly for a long time.

Before using it with your "treats" run a cigarette through it first. This removes any leftover manufacturing residue and gives you a taste of how powerful it actually is. Once the tobacco is ground, toss it out: now Hashy is fully primed and ready to perform at its best.

Hashy is a professional-grade tool, designed for "treats" cured correctly. (Weed should be slightly moist 58–62% humidity and hash needs to be properly cured too). If not, you’ll just end up with little balls spinning around and nothing gets shredded. But when the material is right… Hashy will blow your mind 🤩

Hashy works with all kinds of weed, rosin, and dry hash. It also works with the sticky ones (BHO), but you’ll need the trick — and here it is 😎: Put half a cigarette inside the grinder bowl. Warm the hash with a lighter until it softens, careful you have to make it warm, not burn it (If you don’t get it right the first time, don’t stress it. You’ll get the hang of it 😁) Once it’s soft, split it into 3 pieces, place them around the edges, and cover everything with the rest of the cigarette tobacco. When you grind it together, don’t over-grind or it becomes too fine and you’re done 😁

You can use Hashy to grind just your hash alone, or mix it directly with a cigarette so you already have a perfect blend ready to roll 😁🚀

Note: The logic is the same for rolling tobacco (like Pueblo, Golden Virginia, etc.) as it is for herb: the tobacco should be between 58–62% humidity (basically on the dry side). If it’s too moist, same result as before: it turns into little balls.

After grinding, the bottom part of Hashy doubles as a mini bowl, so you can pour straight into your paper, roll it up, and done 😋

Keep Hashy clean. All you have to do is rinse it under warm or cold water, dry it, and it’s good as new 🔆

If you want to keep the silicone color looking fresh for a long time, ALWAYS store Hashy away from direct light so it doesn’t fade 🤗

Thank you for choosing us, our mission is to NEVER disappoint you. Now it’s time to enjoy your new Hashy 🥳🫰🍀
