ダンジョンズ＆ドラゴンズ D20 保温ランチボックス

The little dice-shaped handle and the zipper are more sturdy than I expected, so it’s held up fine on a week of commutes. Being able to toss it in my backpack without worrying about crushed snacks is a win, though the 8.7″ width means it doesn’t fit smaller side pockets.

My lunch group actually stopped to admire this thing—the insulated lining kept my sandwich cold for nearly four hours, and the D20 shape is way more functional than I expected for carrying snacks.

The zipper is sturdy, and the D20 shape is surprisingly roomy for a full day of snacks. I've been using it for work lunches, and it fits a sandwich and chips with room for a drink.
