Where to find removable vinyl not made by Cricut? (Does it exist?)

Hi all, I'm looking to make flexible stencils (one time use) for use on painted walls. I've read on this sub that I should be using removable vinyl but all I can find is permenant vinyl - except for the removable vinyl made by Cricut themselves. Does anyone know of any other brands that make removable vinyl? In the UK.

Any tips for a first time stencil maker welcome. Thanks all
