EDIT: Found my answer after looking for it for quite a while recently! searched correctly.
Hey my sundia shining cups are pretty bent out of shape, i have just got the things to go into the inside of the cups to bend them back into the perfect shape but ofc they just bend back once removed. I saw a post quite a while ago about doing something like putting them in hot water and doing something? can anyone give me the full info im looking for? thanks.
