The "Neco Arc" set features pixelated anime characters with cat ears, red eyes, and smiles, wearing white t-shirts and blue shorts. One is holding a weapon, another is gesturing with their hands, and the third has their eyes closed. The style is pastel and vibrant, anime-inspired, with a cozy atmosphere. They are perfect for light, playful, and cute messages, especially during moments of joy, happiness, or affection.
