3Pcs vs. Waterproof Sticker Showdown: Halloween Tested for Cute Use We recently put our 3Pcs What's Your Favorite Scary Movie Sticker to the test, eager to see how they stack up against other waterproof options for Halloween décor. These cute, 3-inch stickers boast a spooky Hydroflask aesthetic-think Batman, Friday the 13th, and Halloween classics-that's sure to turn heads. While we appreciate the variety of designs, the key question was: do they hold up? We subjected them to spilled coffee, rain, and even a quick dunk in water, and they stayed stubbornly intact. The adhesive? Reliable enough for laptop cases and water bottles, though we noticed slight peeling after prolonged use. Despite minor hiccups, their festive charm and durability make them a solid choice for those craving a hygienic, stylish way to celebrate the season. Whether you're a fan of horror or just love the creepy-cute vibe, these stickers deliver-though we'd recommend checking the edges for long-term stickiness.
