These are envelopes for wedding thank-you gifts and transportation expenses, with a "結び切り" (musubikiri) knot design. "寿 (Kotobuki)"... I used one for a speech thank-you. There are 3 left. This type is for gifts of 10,000 yen or more, and keeps the bills from folding. "お車代 (Osharyodai)"... I didn't use these. This type is for keeping bills from folding. There are 2 left. "ポチ袋 (Pochi-bukuro)"... I used these for thank-you gifts to the reception staff and performers. This type is for gifts of less than 10,000 yen, and requires bills to be folded in thirds. The retail price for all three types is 1200 yen.
