Background

Interferon lambda 3 (IFN-λ3), also known as interleukin-28B (IL-28B), is a type III interferon that plays a crucial role in the innate immune response against viral infections. IFN-λ3 is produced in response to viral stimuli and exerts potent antiviral effects by inducing the expression of interferon-stimulated genes (ISGs) that inhibit viral replication and spread. Similar to other type III interferons, IFN-λ3 signals through the IFN-λ receptor complex, which consists of IL-10R2 and IL-28Rα subunits, leading to the activation of downstream signaling pathways involved in antiviral defense. IFN-λ3 has been implicated in the immune response to various viral infections, including hepatitis C virus (HCV) and influenza virus, and is considered a promising therapeutic target for the treatment of viral diseases.

Salt or pepper grinder.
Color: Silver1
Excellent product. I accidentally broke one of mine and was pleased that I was able to purchase one grinder. They’re beautiful and very well made. Grind salt and pepper easily and many different coarseness. And they are pretty.

Inexpensive but certainly not 'cheap'
Color: Silver1
These work well and feel like very good quality far in excess of what you might expect for the price. I am very happy with my purchase.

great but one flaw
Color: 1pcs-Sliver-304
almost everything about this pepper grinder is perfect. the glass the turny bit and how easy it to use and clean is great. its such a simple and accessible piece of kitchen utility and its pretty in its simplicity too BUT! there is a little plastic ring that keeps popping out as i use it. the peppercorns will get stuck behind it and work it out every time i use it and it falls out into my food about every other time so i have to keep popping in and out that little plastic ring and clearing out the pepper and hoping i don't lose it or eat it.

Perfect Compact Size and Smooth Efficient Grind
I absolutely love these salt and pepper grinders! They are perfectly-sized, less cumbersome than most 12"+ sized grinders. They're wide enough to hold more than it looks like they hold, which means less refilling required. The grind is smooth and flawless - it usually only takes me one quick single-hand- motion to season my plate. I use pink Himalayan salt, and black peppercorns, and can adjust it easily to suit my or my husband's grind preferences. These grinders are pretty enough to set out on a table for dinner guests, while being quick and efficient for ourselves.
