Superfrozen upon packaging. Store in conventional freezer, for best results and to reduce chance of oxidization (color change) please consume immediately or within 1-2 weeks.

Do not refreeze. FYI-- we love using our forgotten thawed uni for a creamy pasta sauce!


Defrost in controlled refrigerated temperature (28-32 degrees fahrenheit) for 6-12 hours or until texture reaches your desired preference.

Pro Tip: Place near the back of the refrigerator so temperature remains more controlled despite repeated opening/closing of the refrigerator door.

Riviera Seafood Club's Wild-Caught Uni, also known as Sea Urchin, is sustainably and responsibly wild-caught in Mexico, USA, Canada, or Japan. Uni presents a deep, rich ocean flavor and is very high in umami flavor as well; it is complemented by a delicate, creamy, and buttery texture. Our Sea Urchin is of the highest quality sashimi grade delivering an unrivaled flavor profile with a softly-sweet brine on the finish.

All orders of Wild-Caught Uni (Sea Urchin) are individually packaged and shipped using express overnight delivery. Each 100 gram tray packs 10-15 roe are hand caught by divers off the Pacific coastal waters from Canada, California and Mexico and delivered to your table in two days (one day for processing, one day for delivery). Uni is an extremely delicate seafood. In order to guarantee our freshness, each shipment is packaged securely to maintain proper temperatures. If you are intending to consume the seafood raw, do not freeze as this will ruin the integrity of the uni.We guarantee that our wild-caught uni (sea urchin) is the best quality that you can find, perfect for sushi, sashimi.

Time your defrost process to a couple of hours before your meal for the optimal outcome.

Yes and no. Yes, you can refreeze it for a future cooking preparation. No, if you plan on using it for raw preparation.

Yes! We suggest that most super-frozen products may be stored in a conventional freezer for up to 2 months upon usage.

The United States is late to the game... Many countries, including Japan, depend on this technology to assure minimal loss in quality and maximum gain in shelf life.

Always a reliable source to buy sashimi grade Uni & other cuts.
Bought the 100oz last week, it was so good, I just bought 2 more packs for this week.

Penelope Memoli
Tasted fishy and made me sick.

The package arrived in good condition and nothing seemed off. I’ve had sea urchin and sashimi many times. Did not expect this to make me ill but I was sick for two days and I don’t think I could stomach sort of sashimi or sushi for quite some time. Sad because I really enjoy Japanese food.

Sickness is never acceptable at RSC! Shipment delayed by FedEx, causing spoilage. We have pursued claims with shipping courier and remedies with customer privately.

Daniel Sawler
Deceitful shipping fees

I bought two items totaling $60 plus. I didn’t get to see the shipping fees until after I placed the order. Over $ 65 in shipping? That is EXTREMELY OUTRAGEOUS!! I told you initially that I will not be doing business with you again. I am also going to share my experience with your company with everyone that I know! And social media is very powerful!!!

Thank you so much for reaching out and providing us with this feedback!

As a small company, unfortunately we do not have the most competitive rates with shipping couriers such as FedEx and UPS, like bigger companies normally would. We know this is a factor for all of our customers, so we are constantly evaluating and renegotiating our rates with them as we grow our shipment quantities. In the meantime, we do offer free shipping order minimums if you ever want to share an order with friends/family. We can also separate and split the orders within the shipment if you let us know after placing your order. We do also frequently offer promotional discounts to our customers-- which you can stay in the loop on via email newsletter or on our Instagram and Facebook pages (@rivieraseafoodclub).

Please let us know if there is anything else we can help you with in the meantime!
