The DIY Number Balloon Kit - perfect for birthdays at any age, even half birthdays.  A simple, yet always beautiful, white globe balloon complete with a number sticker (in Helvetica, obviously). 
 
Easy to make in just a few minutes (or even seconds if you're really speedy). 
 
This kit includes:
- One 18" white globe thick, latex balloon 
- One number transfer sticker 
- 1 metre length of biodegradable raffia ribbon
- Full instructions
- A lolly stick 
 
The balloons in this kit are suitable for use with either air or helium, and the best bit about attaching your own number is that it's up to you which way you float your balloon (knot up or down!). 
 
Float time with helium: up to 12 hours+ 
When inflated with air, balloons can last several days with little deflation when kept in optimal conditions. 
 
Need to know:
- Keep your inflated balloon at room temperature, and away from very warm or very cold temperatures
- Balloons don't love direct sunlight 
- Keep your balloon away from sharp objects 
- Once deflated, cut up your balloon into tiny pieces and place into a general waste bin; or even better, add these tiny pieces to your garden mulch or compost bin 
- Re-use your number sticker! Stick it to the cover of a notebook and keep a journal for the year, or attach to the gift wrap of a friend's present when they turn the same age.
 
- Deflated balloons are a choking hazard!
- Balloon strings are also extremely dangerous. This is not a toy, and children must not be left alone with a balloon. Adult supervision is necessary!
- Never ever release balloons into the environment
