Is this ornament glass or resin?

It is molded resin, not glass. Resin takes fine sculpted detail and survives knocks better than blown glass, though it can still chip if it falls onto a hard floor.

Does it come with a hanger or string?

It has a hanger attachment at the top, so it hangs on a tree branch hook or loop. A decorative ribbon or string is not included.

Is it safe for a tree with young children?

It is a decoration, not a toy. Small parts and painted details mean it should hang out of reach of toddlers, and it is better placed higher on the tree.

How does it compare with Hallmark Keepsake ornaments?

Keepsake ornaments are the collector line, often dated or personalized and sold in sturdier display boxes. This one is a simpler licensed design aimed at Disney fans rather than year-by-year collectors.

Can it be personalized or engraved?

No. The piece is a finished painted resin figure with no plaque or flat area meant for names or dates.

It is a standard tree-ornament size meant to sit among other ornaments, not a large statement piece. Check the listed dimensions if you need an exact figure for a small tree.
