Tick... tock... tick... tock! Your guests will be counting down the minutes until the party starts when they see these holiday party invitations. The circle shape makes them a standout from the start, and you can choose from over 70 colors for the green clock details and the pattern on the back. You can also choose what hour the clock hands are set to! All the text on the back is editable, so create your own rhyme, or use ours to set the theme. Then just add your party details to finish personalizing these New Year's holiday party invitations. Square envelopes are included, which do require extra postage. Rectangular envelopes also available that do not require extra postage.
