Make the pack feel complete
A Telegram-style pack should cover enough reactions for a real conversation: happy, sad, shocked, angry, love, sleepy, thinking, please, thanks, and laughing.
Keep one visual identity
Users are more likely to remember a pack when every sticker looks like it belongs to the same world, character, or illustration style.
Use preview pages for discovery
A web preview can show the full set, help search engines understand the topic, and guide users toward the app when they are ready to save the pack.
