Chilly's is a company based in the UK. The products are manufactured in China

No spare parts received, I don't know if they can be ordered.

Please excuse this mistake on our part. We have now corrected this and now the bottle can also be ordered individually. :) Thank you for pointing this out.

Regrettably only 500 and 750ml

The Chillys brand has been around longer than FLSK bottles. Difference: FLSK has an additional copper coating on the inside, which keeps warm drinks warm for 3 hours longer than Chillys. Chilly's does not want a copper coating because they are against copper mining and the associated child labour.

No, Chilly's bottles are not suitable for dishwashers. https://chillysbottles.zendesk.com/hc/en-us/articles/207411249-Can-you-put-Chilly-s-Bottles-in-the-dishwasher-
