We named our mini card line “Notta Lotta Room to Write” for a reason. Perfect for the person who just wants to pen a quick message. The cards measure 3.5” square and they are blank inside. Pop it into the 4” square envelope and you have an adorable little card to go with whatever gift you can dream up. One thing to note is that these envelopes are too small for the post so you will need to use a bigger envelope if you want to mail it.
