Absolutely wonderful
Size: 3 Ounce (Pack of 4)
The most beautiful, delicious smoked oysters I have EVER had, and I've been eating tinned smoked oysters since I was a child in the 90's. And South Korea had very strict laws regarding the sustainability and quality which go into the oyster farming, harvesting and processing, making these a conscious and clean pick, and where else can you get these beauties tinned in healthy olive oil?! Thank you Otter Kingdom!

If you like smoked oysters, you'll LOVE these
Size: 3 Ounce (Pack of 12)
These are absolutely the best smoked oysters I’ve ever had. There’s a subtle sweetness underneath that adds a pleasant balance to the smokiness, and the usual seawater “fishy” note is far less pronounced than in many other premium brands—which I find refreshing. No unpleasant aftertaste, either. And as shown, they’re huge!
I think I’ve found my new favorite brand of smoked oysters. I don’t write reviews very often, but Otter Kingdom Premium Smoked Oysters definitely deserved the praise.

These are delectable oysters & love that they're in olive oil!
Size: 3 Ounce (Pack of 12)
Our family has been eating oysters for years, but this Otter Kingdom brand has to be the tastiest ever-- tender and flavorful-- Highly Recommended. Re: what a previous reviewer had posted: “These oysters come with a Prop 65 “Reproductive Health” warning on the packaging.” After looking into this Prop 65 warning, I found that most products that come from the ocean could have absorbed mercury, so this California Prop 65 label is stuck on a lot (if not all) of fish/seafood products. But each kind of fish/seafood has a different level of exposure. According to the LiveStrong website article: “Which Fish Has the Highest and Lowest Mercury Levels?” the seafood with the lowest mercury content includes: catfish, clams, crab, herring, OYSTERS, salmon, sardines, shrimp, tilapia fish, tuna fish, among others. These should be eaten no more than 2 to 3 times a week (most people stay within that guideline). It’s the larger-sized fishes that tend to have higher mercury content, so oysters are of no more concern than any other small fish. Just wanted people to not get out bent out of shape about this label. The State of CA has a lot of concerns to deal with-- like wildfire devastation caused by their policy to restrict water from flowing from the north of the state, so it would probably be better for them to focus on THOSE life-endangering issues rather than sticking all these "WARNING" labels on food products! Right?

I Love oysters
Size: 3 Ounce (Pack of 4)
These oysters are very good tasting. I eat them with pasta and a few tablespoons of white Alfredo sauce. Yum yum. I've always liked oysters but I can't eat them raw anymore because of my immune system.

Stable, solid, and versatile!
Color: Black, Size: 8 Panel-176'' Wide, Color: Black, Size: 8 Panel-176'' Wide
Exceeded my expectations. Easy, but tedious to assemble. That said, it’s solid, well made, and will last. You can stand it up in a straight line without concern it will fall over. No need to fold it like an accordion for stability. Helped me separate my garage gym from the kids bikes, shelving, paint, tools, and typical garage stuff.
