Now, 31 ice cream is doing a campaign “HAPPY 4 YOU” to celebrate their 40th anniversary. You can pick up 4 flavors. The size is a little smaller (about 70 percent) than kids size but you can have 4 flavors! Moreover it just costs same as small double but the volume is 40 percent bigger than it. How profitable! I recommend you to have “caramel purerin cream” as a one of your choices. Be careful, the campaign will be until June 28th! HURRY UP!
