Can I put a name on it?

Yes. The listing is for a personalized version, so you add the name or short message you want printed. Keep it short so it fits the shape.

Which shape should I pick?

Snowflake is the smallest at about 2.6 by 3 inches; star and heart are the widest at roughly 3.2 inches; circle is about 2.76 inches square. Pick by the design you want framed, not by size.

Is it real porcelain or plastic?

It is 3 mm porcelain with a printed design, not plastic or resin. That makes it lighter than ceramic figurine ornaments but more fragile than wood.

Can it hang on a real tree?

Yes. Each piece has a drilled hole with a gold-toned string, and at around 3 inches it sits fine on normal branches. The hole position can vary slightly from piece to piece.

Wipe dust off with a clean, dry microfiber cloth. Do not soak it or use water, since the print is on the surface.

Is it a good gift for a Barbie collector?

It works as a small themed gift or a named keepsake, but collectors usually want boxed, branded pieces. Treat this as a personal ornament, not an investment.
