Buying Guide

Choose kits sized for your display

Select a kit or number size that matches where it will be shown—large 3ft marquee numbers work for walls or centerpieces, while smaller options suit tabletops

Prefer light-up or reflective elements

Kits with light-up components or reflective sequins make mosaics stand out in party lighting and photos

Check mounting and display options

Look for wall-mountable or freestanding designs so pieces can be reused as backdrop decor, table props, or photo-ops

Factor price and rating together

Compare the (price varies) price point and 4.1★ average rating among popular marquee-number products to judge value for materials and finish

Match theme and age appropriateness

Pick colors, numbers, and ease-of-use appropriate for the child’s age and the party theme to maximize engagement and safety
