Okay, so this isn't play-doh, but before that came along plasticine was the original soft modelling toy for kids, and it's just as much fun as it's smellier replacement. Debenhams has a huge 38 piece Plasticine Pots & Pieces Super Set reduced by 70%, down from £25 to only £7.50.
The set contains 24 tubs of plasticine, and 14 modelling accessories, which should keep the children occupied for quite a while. There's also an ideas and instructions leaflet if they get stuck for inspiration. This set is still selling for £19.99 on Amazon, so you're getting a bit of a bargain by ordering it from Debenhams.
Home delivery will add an extra £3.99, or you can click and collect for free from your local Debenhams. So, what will your children make with all that plasticine?
