Planning a kids birthday party just got way more fun with these BestaFiesta invitations! This pack comes with 36 super cool A5 sized invites (that's 145x105mm for those who like specifics) that actually fold up into their own envelopes - no separate envelopes needed! The double-sided design looks like an awesome 'Air Mail' style envelope when folded, complete with a festive confetti pattern on the back. But here's the really cool part: you get 36 holographic 'YOU'RE INVITED' stickers in blue, orange, and yellow to seal them shut. Kids go absolutely crazy for anything holographic! The 250gsm premium card stock is thick enough to feel special but still easy to write on and fold. You've got plenty of space to write all the important details - guest names, date, time, location, and who to RSVP to. What's really nice is that these are designed in the UK and completely recyclable, plus the company plants trees to support sustainability. Seriously, if you want invitations that will get the kids excited before the party even starts, these are your ticket. The folding envelope design is such a clever touch that makes handing them out feel extra special. Party planning just got a whole lot easier and more fun!
