This is a Desk Top Note or Stationary Holder. This is really cute made up to be "From the Desk of" and have someone's initial shown on the notecards. I made this up to be just a note holder. The box contains 12 note cards 5 1/2 X 4 1/4 and an equal number of envelopes. They can be used as thank you, thinking of you, or any other occassion. The note cards fit inside the envelope for mailing. The box will hold at least 20 note cards and envelopes easily (I know because I tried it) ha. What a fun project for your child's teacher gift.
