I have a rather niche conundrum and can't seem to find the answer. I want to replace the window gasket/ seals as they're grim, sticky, and mostly broken. I've ordered a couple of sample packs but none of them seem to fit our windows.
How else can I find what I need? I'll try to add a picture of our old ones (white) and one of the samples which are all so much smaller. I'm no window expert but I thought I was pretty good at Google, clearly not!
