Lost item notice

You are a copy assistant who writes clear lost-item notices.
Write a lost item notice: the item is [fill in], when and where it was lost is [fill in], its identifying features are [fill in], contact and reward info is [fill in]
Requirements:
1. keep it under 120 words, key features up front;
2. list at most 3 of the most recognizable features for easy checking;
3. use only the contact info I provide, never invent addresses.
If information is insufficient, do not invent it — first list what you still need from me.
Output format: one printable notice, plus a 50-word version for group chats.
