HIC Kitchen's Adjustable Spice Grinder with ceramic mechanism crushes and grinds flaxseed and all types of spices. The grinding mechanism quickly adjusts from coarse to ultra-file with a simple turn of the locking nut for easy customizing. Keep spices at the ready. Its unique design grinds upside down and stores contents right-side up. The lid keeps contents fresh longer between uses. It's ideal for flaxseed, sesame seeds, coarse salt, peppercorns, dried herbs, and more. Made from glass, ceramic grinding mechanism, 18/8 stainless steel, and BPA-free plastic, HIC Kitchen's Adjustable Spice Grinder is sturdy, durable, won't react with contents, will never dull, corrode, or rust, and disassembles to wipe clean. Brought to you by HIC, a third-generation family owned and operated company in the USA since 1957.
