Anyone know the details of boxed frozen 16-20 shrimp at Costco?

A few months ago I bought a box of frozen raw 16-20 shrimp with heads on. It was in one of the frozen food cases with glass doors and contained about 50 shrimp at a really good price. The box was white and maybe 12”x8”x2+”.

I should have taken a pic of the box but didn’t. I’ve been Googling but not finding anything associated with Costco. Now, with Covid even more of a fear, I’m going back to shipping and delivery services wherever possible. If anyone has specifics (brand, etc) on this product I’d be grateful.

I’m in SoCal (OC) but that’s not an issue at this point, except as a reference.
