And it weighs 65 pounds. There is a warning label.
Distributors started delivering them around the college town last Friday. The pack, which features a special plastic lining that can hold ice like a cooler, has already sold out, the Baltimore Sun reports.
The 77-pack of the beer affectionately called "Natty," and known for its entry level price point, is selling for around $30, the Baltimore Sun reports.
Distributors only expect to have them available for a couple more weeks.
"It was selling out as our guys were delivering it off the trucks," Eric Best, general manager for a Maryland-area beer distributor, told the Baltimore Sun.
He said they distributed about 200 of the packs and expect to deliver more soon.
Best told the Sun the beer maker chose the area because it was one of the brand's first markets when it launched in 1977. Natural Light did not comment.
