Can't find a link to it on their site, but seen today in Poundland Hemel they have 6 mini Jelly moulds just like the ones in the pic, only difference is the colours are slightly different. They come in a drawstring net bag.
I have bought the Tala ones earlier this year and they retail normally for about £4 upwards. So this is a good saving for something you might only use once, hey they're not just for xmas!!
