Copper wire solar lights-aaaargh!

[namechangedtemporarily123]

I love these lights but I absolutely hate untangling them whenever I string them up. I used to get a brand from Amazon where they were looped round a piece of cardboard but I can't seem to find those any more. Any recommendations?

Tesco are looped round cardboard.

You can cut out your own piece of cardboard then you have to untangle them only once.
