~From the product description~ "Oru Sand" is a folding case for sandwiches made with a single slice of bread. Open it up, place your bread (or toast) and your favorite fillings, fold the bread in half with the crusts still on, and close it to create your "Oru Sand." You can open it from the side and eat it without getting your hands dirty. After you're finished eating, fold it up compactly to take it home, wash it, and reuse it. Recommended for lunches, snacks, or even breakfast for family members with staggered mealtimes. Made in Japan. Not dishwasher, dryer, or microwave safe. Set of 3 vitamin-colored pieces. ★ I am selling a new, unused item that I purchased as a spare. ~Impressions (personal opinion)~ Convenient once you get used to it. It's more like making something similar to a "____ dog" using bread rather than a sandwich. (It can hold voluminous fillings.) If you put in mayonnaise or something similar, the case will inevitably get dirty, so I think it's better to have some plastic wrap if you're taking it home. #SummerVacation #LunchBox #LunchBOX #TimeSaving #Sandwich #MadeInJapan
