Want to let your children know you are thinking about them when they are at school, but have little time to jot a note for their lunchbox? Now you can buy mini note cards called Mommy Messages for just that purpose.

Two sisters came up with the idea for the cards that express sentiments such as “I’m thinking of you” and “Have a special day.”

The sisters, Jill Franks and Alison McKinstry, remembered how much they loved finding hidden notes from their mom when they were growing up, and they wanted to do the same for their kids, according to their website.

Their business is called Good Stuff Products, and the cards can be purchased in area grocery stores or online at www.goodstuffproducts.com. They range from $1.95 to $2.49.
