Ever put a permission slip into your child's backpack and hope (and pray) that it arrives safely? Well, you're going to love these Kid Carriers: a preprinted pad of 10 envelopes that allows mom to let your child's teacher know exactly what's being delivered. The colorful design make it easy to spot and the fill-in-the-blank format makes it easy to use. Business envelope size: 4 1/8" x 9 1/2". What a special delivery! Choose from Green and Blue Stripe, or Pink and Green Stripe.
