>>17762808from what I can tell through googling "basic mix" appears to be a common 7-eleven sandwich pack containing ham, tuna salad, egg salad, and lettuce sandwiches. the japanese at the bottom of the pack in the photo calls itself a "sugoi mix" (amazing mix), because it's the same basic flavours but at a significantly higher volume. the sandwiches in the picture also appear to be from lawson, which is a competing convenience store chain to 7-eleven in japan. so in a way lawson is trying to copy 7-eleven's "basic mix" while also doing it better
