Paper muffin cases for cupcakes vary in quality - which do you recommend?

[bacon]

I use the muffin cases as I find the smaller cupcake ones too small and I like to give a good coating on top with icing/granche etc.

I find the paper quality seems to kink/fold look awful. While another set of black greaseproof waxy style ones keep really upright and look professional.

Have anyone else noticed this and now avoid the standard paper ones?

Do you source yours from professional stores/ebay?

I get mine from Asda, bigger muffin ones, some kink and some don't (not really done an in-depth investigation )

What does help is a proper big muffin tin, but I only have one which causes problems when I batch bake....

Liking the idea of professional cupcake cases

I bought mine on ebay, pack of 500 and they were good quality, off course I can't remember seller's name but think it was about a fiver.
