This is the refill box for the TYBO Design Studio from Mookie. The packaging says 'includes 3 bright colours': blue, red and yellow, each with its own squeeze bottle, together with the elastic bands you use to tie the garment off.
You dissolve the powder in the matching bottle, knot up a T-shirt or a pair of socks and squirt the colours into the studio's orb. Three gets you further than you would think: where blue and red meet you get purple, red and yellow give orange, and that happens by itself wherever the dyes run together.
Note what is and is not in here. This is the dye, the bottles and the elastic bands only. The design studio with the clear orb and the turning handle is sold separately, and you need it to use this.
The box says from 6 years. Handy to add straight away when you give the studio as a present, or as a small gift for someone already working with it who has run through the first colours.
