Giant tubs of macaroni and cheese may have met their match.
There's a new super-size product at Costco – giant lobster claws.
Shoppers have been sharing photos of the massive crustaceans on Instagram, some shown with Costco's Kirkland brand on the label.
On Monday, Instagram user @julesfood shared a photo of a 3-pound claw, which tagged Newport Beach, California.
"I’ve seen a few big claws at Costco before, but this one’s crazy!" the post said. "We just had to get it. It might be 1/2 it’s weight in shell, but worth it already. The family’s had their fun photo ops, now it’s going on the grill ... I hope we have enough butter."

Costco is known for selling super-sized products.
In January, the wholesaler sold out of Chef’s Banquet Macaroni and Cheese Storage Bucket, a 27-pound bucket with 180 servings of the comfort food.
On Wednesday, the product was available and selling for $89.99.
It also has a 20-year shelf life and comes with six 30 serving zip-sealed pouches of Cheddar Sauce Mix and six 30 serving zip-sealed pouches of Elbow Macaroni Pasta.
