A review for Transfer stickers by Petrut Malaescu.
Colors are accurate, the glue is strong, the material is a plastic/vinyl that stretches over surface imperfections.
The glue of the transparent backing is strong also, could be less so.
Delivery through Romanian Post (Posta Romana) was almost a month slower than estimated, but that's the post's fault, not StickerMule's. If you see destination in Romania, through Posta Romana you could add a disclaimer: "Orders processed through this delivery service can take up to 30 days longer than estimated due to corruption and incompetence"
