Check capacity and dimensions as well as appearance. Handmade mugs and bowls can vary slightly, and the listing should explain whether each piece is unique or selected from a small batch. Confirm that glazes and clay bodies are food-safe when appropriate, and review microwave, dishwasher, oven, and freezer guidance.

Look for comfortable handles, stable bases, and forms suited to the intended use. Decorative or devotional ceramics may not be designed for food or open flame. Shipping protection and the seller's breakage process are important for fragile work. If you want a matching set, ask how much variation to expect across pieces.
