HOME COMPOSER Happy Birthday Yard Sign Kit — 16‑Piece 15‑inch Letters, Weatherproof Corrugated Boards & Writable Whiteboard

HOME COMPOSER's 16-piece Happy Birthday yard sign kit is a weatherproof, reusable 15-inch corrugated-board letter set with stakes, a writable whiteboard panel and three real balloons to create an instant outdoor birthday display.

Make birthdays unmistakable from the street with a bold, colorful message that installs in minutes. This kit includes each letter of “HAPPY BIRTHDAY” in patterned, multicolor designs, plus a cupcake and gift-shaped accent, a blank whiteboard for a custom note, three balloons and ground stakes. The panels are made from 4mm corrugated plastic, designed to withstand rain and sunlight while remaining light enough for easy placement and storage.

How easy is it to set up the yard letters?

Assembly is straightforward and requires no tools: each panel has a corrugated groove that accepts the included metal or plastic stakes. Slide the stake into the board, then press it into the soil at the desired angle. The lightweight panels let one person arrange the display quickly.

• Insert stake into corrugated gap on each letter panel
• Push assembled unit into soft ground or use additional support in hard soil
• Mix letters and accents to craft your preferred layout
• Write a short custom message on the whiteboard with a dry-erase marker

Will these outdoor signs hold up to weather?

The letters are die-cut from 4mm corrugated plastic, giving them a balance of rigidity and water resistance suitable for short- to medium-term outdoor use. Their printed surface is designed to resist fading from typical sun exposure, and the boards shed light rain without warping. For long-term protection, store indoors when not in use and avoid prolonged UV exposure.

• 4mm corrugated plastic resists water and light bending
• Vibrant printed patterns for visual impact from the street
• Removable real balloons add dimension without adhesive
• Store flat indoors between events to extend lifespan

What customization and extras come with the kit?

Beyond the letters, the kit includes decorative accents and a writable whiteboard to personalize each celebration. The whiteboard accepts standard dry-erase markers so you can add age, a name, or a short message. Three real balloons give a pop of height and texture; tether them to stakes or tie to the panels for a layered look.

• Writable 15" whiteboard panel for custom messages
• Three real balloons to attach for extra volume
• Cupcake and gift-cutout accents for playful detail
• Mix-and-match multicolor letter patterns for a lively display

How should I care for and store the sign set?

Cleaning and storage are simple: wipe panels with a damp cloth for dirt and use a dry-erase eraser on the whiteboard. Keep items flat in a cool, dry place to avoid bending, and deflate or remove balloons before packing. Proper care preserves color and board rigidity for many celebrations.

• Clean with mild soap and water; avoid abrasive cleaners
• Dry completely before storing to prevent mildew
• Store flat to maintain shape and prevent creasing
• Replace balloons as needed for fresh appearance

Who is this kit best for? HOME COMPOSER’s yard sign set is ideal for parents, neighbors, community organizers and small business owners who want an affordable, eye-catching outdoor birthday display without permanent installation. It works well for front-yard surprise parties, apartment balcony celebrations, daycare centers, neighborhood greetings and storefront promotions where a cheerful, readable message is needed quickly and removed easily afterward.
