Generic sticker lettering. Not a licensed product label or character brand.
Why sticker outlines work
A wide black stroke keeps white letters visible on photos, videos and patterned paper. Luckiest Guy is a free Google Font with a comic display shape.
Craft use
Download PNG with transparency, drop it on a photo in Canva, or print for die-cut stickers. Avoid tiny type; the outline needs room.
