How big are these ornaments compared with standard ones?

Each ball is 3.9 inches in diameter, close to a softball. That is noticeably larger than the typical 2.4 to 3-inch tree ball, so they read well from across a room.

Are they glass or plastic?

They are a lightweight ball ornament rather than blown glass, which is why they are a reasonable pick for homes with children or pets. Treat them as decorative, not toys.

How many do I need for a 7-foot tree?

Six balls cover only a small part of a 7-foot tree. Plan on several sets, or use these as accent pieces among smaller ornaments.

Can I hang them outdoors?

They are made for indoor tree use. Wind, rain and sun will dull the finish, so keep them on a covered tree or indoors.

Do they come with hanging strings or hooks?

They have hanging loops built in, but caps and loops vary by set. Check the box contents for hooks or strings before you plan to hang them.

Is the color mix the same in every set?

Multicolor sets usually follow a fixed assortment, but exact shades can vary slightly between batches. If you need a precise palette, order all your sets together.
