Over the years, both Coke and Pepsi have gone through so many packaging redesigns that a new design (not to mention a new version of soda) is almost expected every 18 months. However, the shape of the bottles don’t change quite as often.

This week, Pepsi announced its latest packaging redesign for its 20-ounce Pepsi bottles. According to an Associated Press report, the bottom half of the bottle will now have a contoured shape, and the label has been cropped. The new design will be adopted for Pepsi, Diet Pepsi, Pepsi Max, and Pepsi Next. The design will also be adopted for Pepsi’s 16-ounce bottles.

The new bottles will reportedly begin showing up in gas stations and vending machines starting in April. A Pepsi spokesperson told the AP that the design of the Pepsi bottle shape hasn’t changed since 1996. Pepsi bottling plant manufacturing lines will have to be converted to produce the new shape.
