These thank you cards are perfect for getting your kids to actually write thank you notes after birthdays or holidays! You get 25 cards total, each measuring 4x6 inches which is plenty of space for them to fill in their message. The chalkboard design is really cute and unique - way more fun than boring plain cards. The matte cardstock is thick and durable, so it won't tear easily when little hands are writing on it. The fill-in-the-blank format makes it super easy for kids who might not know what to write - there are prompts for who the gift is from, what the gift was, and a space for their personal message. The back has a matching design too, which is a nice touch. No envelopes included, but that's actually fine because you can usually find generic ones that fit. I've used these for birthday parties and holiday gifts, and they always get compliments. The kids actually enjoy filling them out because the design is fun, and it teaches them the importance of saying thank you. Much better than trying to get them to write on plain stationery!
