This flat-vector kids birthday invitation is a primary-colour celebration in the truest sense: a bright white card set in bold geometric lettering, with TIME TO PARTY stacked centre-stage in heavy ink, a bouncy script greeting above it, and a shower of navy, red, golden and sky-blue confetti stars, dots and streamer strips framing the edges. A red-and-gold party popper fires across the top corner, and a thin navy rule with a single red star divides the headline from the event line below. The guest page carries the same energy: the invitation arrives inside a punched ADMIT-ONE party pass with a gold stub and perforation seams, the countdown reads as one ticket strip, and every panel wears the card's hard sticker shadows in red, gold, sky and navy. The honoree's name leads the page at display scale, and the RSVP ends on the Confetti Club's dark navy stamp wall with a drawn party popper that fires its burst once on scroll. Perfect for a 5th, 6th or 7th birthday party, a school-age celebration, or any loud and joyful kids gathering where the plan is confetti, cake and cannonballs of glitter. Hosts can personalise the date, time, venue and RSVP details, add a guest map with directions, and collect replies with the built-in RSVP form. Whether it is an at-home bash or a rented party room, this invitation sets the tone: bright, bold and ready to pop.
