50 Joseph Joseph Intelligent Waste IW2 Food Caddy Liners 4L 5 "Other bags simply won't do!" Ms Taylor 17 July 2015 I'm the sort of person who, in the past, might have used bog-standard supermarket bags in my food caddy liner. No longer! I have no idea what material these food caddy liners are made from, but they open beautifully and feel like silk under your fingers, and are definitely worth £8.99. If you've splashed out nearly £200 on the bin (and if you haven't, you really should), consider spending a little extra on these liners to make the experience complete. I don't know what this says about my life, but I actually think "Hurray!" when I get to open a new one. Highly recommended.
