GIANT '21' NUMBERS
Our '21' light up numbers stand 1.2m tall, steel fabricated with a gloss pearl white finish and warm white bulbs. Want them pink, blue or anything in between? Our remote control coloured bulbs and set the colour on the night.
We hold multiple sets of '21' in both Melbourne and Brisbane, so busy Saturdays are covered. Peak dates still go early, so book once your venue's locked in.
Pricing is all-inclusive of delivery, setup, collection and GST. '21' numbers start from $300 per set in Melbourne and $350 per set in Brisbane. Home, backyard, function room or venue, indoors or out.
We deliver across Melbourne, Geelong and Ballarat, and Brisbane, the Gold Coast and the Sunshine Coast. See delivery areas.
ADD A BACKDROP
Most 21sts pair the numbers with a backdrop so there's a proper photo spot, not just numbers against a wall. The pairings that book most:
-
'21' numbers + balloon garland
-
'21' numbers + shimmer wall or flower wall
-
'21' numbers + neon sign on an arch with faux florals
Or book it in one go: our 21st birthday packages bundle numbers, backdrop and neon from $450.

"From the first phone call and right up to delivery, Big Light Letters listened and accommodated my requests. They were very easy to work with, and I have no reservations about recommending them to friends and family!
The light up numbers were classy and looked amazing, and together with the balloon garland were the perfect backdrop to all our photos. I will definitely be using them again for future functions!"
