Celebrate a 21st birthday with this neon glow party invitation that lights up from the very first tap. The design comes straight from the printed card: the name in chunky marquee-bulb letters, each letter a different neon colour filled with round white bulbs, BIRTHDAY PARTY in matched purple neon outline, a glowing glow party still life, dotted neon-pink dividers and neon light rings on a deep midnight ground. The guest page keeps the whole show: the bulb letters pop on and flicker, BIRTHDAY PARTY hums in purple neon, the card sits on a dark mat with a neon tube edge and the glow party props at its corners, every fact sits between dotted pink dividers in cyan and white, a hot-pink band shouts the age, the countdown ticks in four neon tiles, the map has one-tap directions and add-to-calendar buttons, and the RSVP is a glowing hot-pink pill under the glow party mascot. Every reply lands in the host dashboard with a live guest list, headcounts and reminders, so nobody has to chase replies by text. The matching print bundle includes a welcome sign, a photo booth frame, a guest book page, a colouring sheet and party bingo in the same neon style. Built for a 21st birthday and ready the moment you add your details. Perfect for glow party parties, glow parties, movie nights and any birthday that deserves its name in lights. Share it by link, text or email; it reads perfectly on a phone and opens up on a laptop, and every detail — the name, the age, the date and time, the venue, the host message and the RSVP deadline — is editable in minutes.
