The founders of Mellow Interior have invested countless hours testing the functionality and durability of Mellow’s signature piece. The result? Mellow’s glass grinder delivers a finer grind with greater ease than any other tested product.

To obtain the best possible grinding result, simply place the lower part of the grinder on the table/ in your hand and sprinkle what needs to be grinded. Than place the upper part of the grinder on top and simply rotate to one direction. After 10 sec. you should have an optimal result.

Design: Mellow Interior strives to establish itself as a timeless luxury brand for cannabis accessories and select interior pieces. That is one of the reasons we don't want to use the materials everybody else uses. Glass seamlessly complements any space—not just as a trend but as a lasting design choice. Plus, it’s exceptionally easy to clean.

Quality: Borosilicate glass ensures exceptional durability, heat resistance, and clarity. Unlike regular glass, borosilicate is highly resistant to thermal shock and scratches, ensuring a long-lasting, premium feel. Its non-porous surface also makes it incredibly easy to clean, maintaining the purity of herbs and spices without retaining odors or residues.

The best thing about boroscolite glass is that you can just put it in a dishwasher with all your other tableware. We recommend washing the Products after every 3rd-5th use, so they keep shining all the way.
