Lir Make Your Own Easter Egg Kit

If you wanted to make your own Easter eggs but didn't want to get too messey. Ocado have a 'Lir Make Your Own Easter Egg Kit' for just £3.99 or 2 for £7. I've been into their Waitrose stores and they had a great selection, but I don't remember seeing this one. Can anyone let me know if they've seen it?

The 2 for £7 deal apparently runs out on 25th March, which is Easter anyway.
