Recently, the official Green Day store revealed some new merch. The items, which are available on the US store, include some new T-shirt designs, a button and a baby-sized Dookie onesie, which may well be the cutest merch item Green Day have ever sold.

Despite not being available on the European version of the store, fans located outside North America are able to access the new items by clicking on the flag in the top-right of the page and selecting the US $ option.

The new T-shirt designs feature the 'Green Day' backdrop that has been seen on the band's tour, a photo of the band, and an individual wearing a ski mask. The button bears the familiar Revolution Radio car.

Prices range from $1.99 for the button to $24.99 for the shirts and onesie. More information is available at store.greenday.com, where the items are also available to purchase.
