I’ve been buying the chain I use for my suncatchers from Markylis on Ebay for ever. 4mm x 5.5 mm (though I did have one batch which was more like 4mm x 5mm but it wasn’t an issue).
It comes in 2.5m lengths and is super strong… I can’t break it with my hands - have to use wire cutters and that is exactly how strong it needs to be. Don’t want my suncatchers falling to the ground if the chain breaks.
Problem is that Markylis Ebay say silver is out of stock, can’t find it on their website, no (working ) phone number and no response to my Ebay message.
In desperation I bought some from another Ebay shop. Just filled in a return notice as I can break it with my little finger (hope they don’t mind the 3 inch broken length I will be returning but it’s obviously not fit for purpose).
I have 2metres left …after that I am Stuck.
