Common diameters shown in listings include about 2.35–2.8 inches (~60 mm), about 3.15 inches (~8 cm), and larger 6-inch bulbs. Multi-piece sets often mix these sizes, so available diameters can vary by product.
Many sets come ready-to-hang and include metal hooks, lanyards, or hanging loops so they can be displayed immediately.
Mixed sets commonly include a variety of styles such as textured or striped bulbs, solid-colored bulbs, glitter-covered ornaments, and mirror-style (reflective) bulbs.
Colored ball ornaments are commonly made from glass and from plastics. Listings explicitly mention materials such as glass and PVC (polyvinyl chloride) or general plastic construction.
Pack sizes vary widely: examples include small sets (set of 3), mid-size packs of about 12 pieces, and larger 24-piece sets.
They’re described for use on Christmas trees and for wreaths, garlands, centerpieces, mantels, and similar holiday displays. Some listings also note using them as bowl or vase fillers and for party decorations.
