"Seems to have warped" star star star star_border star_border I bought two tins a few years ago, and I'm very disappointed to find that after only occasional use (once or twice a year), one base seems to have warped. Just made a sandwich birthday cake and have had significant leakage from one tin. Only one so it can't be my batter. I thought I was buying quality that was going to last.

We'd recommend using baking parchment to line the tins to avoid any leakages.
