The "Potato Holder" is a design based on the familiar red color of the McDonald's potato package, and can be used by inserting it into a drink holder such as a car. It is said to be a convenient item for eating "McDonald's Potato" in the car.
The target products are value sets that combine hamburgers, drinks (L), and McDonald's potatoes (L), and salad sets, coupons, happy sets, and shareholder coupons are not eligible. Drinks are also available in latte menu M size such as cafe latte.
In addition, a campaign to solicit new ways to use "potato holders" will be held from April 19th to May 7th on McDonald's official Twitter account (@Love_McD).
