Kids invitation cards include 20 printed colorful invites and 20 plain white envelopes. Invites are flat style, non-folding, and professionally printed in 4.25x6 inch size. Invitation cards are printed in full-color and double-sided on a heavyweight, uncoated cardstock. This material makes writing on invites easy and smooth without smearing as the writing dries instantly. These invites are perfect for kids themed parties.
