Is this ornament glass or plastic?

It is glass with a mercury-style mirrored finish. Handle it carefully when hanging and storing, and keep it away from the edge of a low branch if pets or small children are around.

How big is it compared with a standard ornament?

It is about 5 inches in diameter and roughly 3.25 inches deep, so noticeably larger than a typical 2 to 3 inch ball. It suits a large tree; on a small tabletop tree it will dominate.

Does it come with a hanging string or hook?

It has a hanging loop at the top. Hooks and ribbon are usually not included, so plan on using your own ornament hooks or twine.

Can I use it outdoors?

It is best kept indoors. Glass and a mirrored finish do not hold up well to rain, freezing temperatures or wind, and a fall onto a hard surface can shatter it.

Will the silver and gold match if I order more than one?

Mercury-glass finishes are made piece by piece, so the mix of silver and gold and the amount of distressing can differ slightly between ornaments. That variation is part of the vintage look.
