RAW Hydrostone humidifying stone

The RAW Hydrostone is a small terracotta humidifying stone designed to keep smoking materials fresh or rehydrate dry herbs. It is a signature accessory from the RAW brand, which is world-renowned for its natural rolling papers and commitment to vegan, unrefined products. The stone operates by being soaked in water, after which it gradually releases moisture into a storage container.

RAW was founded by Josh Kesselman, who established the brand in the late 1990s and early 2000s in the United States, but famously sources and manufactures its primary paper products in Alcoy, Spain. The brand is currently under the ownership of HBI International. The Hydrostone itself continues the brand's tradition of using natural, earthy materials, reflecting the company's ethos of sustainable and minimally processed products.
