TONIFUL 52-Piece 16-Inch Black Foil Letter Balloons – Two Complete Alphabets for Custom Phrases

This set of 52 black foil letter balloons from TONIFUL gives you two complete alphabets (A–Z) to spell out custom messages for any party or event. Each balloon measures 16 inches tall, making your banner easy to read from across the room. The kit includes one straw for inflation and two curling ribbons for hanging, so you can start decorating right away.

How to Inflate and Deflate These Foil Balloons

Each letter balloon has a self-sealing valve that keeps air or helium inside without tying knots. To inflate, use the included straw or a hand pump. Fill the balloon to about 90% capacity – overfilling can cause the foil to burst. When you’re done, insert the straw into the inflation hole to release the air, then flatten the balloon for storage or reuse. The self-sealing design makes setup and takedown quick and mess-free.

Key Specifications and Dimensions

Best Occasions for a Custom Letter Banner

These black foil balloons work well for birthdays, graduations, weddings, bridal showers, anniversaries, Halloween, New Year’s Eve, and Valentine’s Day. Their solid black color stands out against most backgrounds and fits both formal and casual themes. Because you have two of each letter, you can create messages with repeated letters like “HAPPY BIRTHDAY” or “CONGRATS.”

Tips for Assembling Your Phrase

With 52 letter balloons, you can form almost any short phrase. Keep in mind that some letters look quite different after inflation (e.g., “S” may look rounder, “W” may stretch). TONIFUL includes printed instructions on the product images to help you identify each letter quickly. Before inflating, lay out the letters you need and double-check your spelling. Inflate the balloons just enough to hold their shape, then use the ribbons to tie them together or attach them to a string.

Common Questions About This Balloon Set

How many balloons come in the set?

You get 52 balloons total: two complete sets of 26 letters (A–Z). This lets you create phrases with duplicate letters, such as “BABY” or “HAPPY.”

Can I fill these with helium?

Yes. The self-sealing valves work with both air and helium. If using helium, fill to about 90% to avoid overexpansion. These balloons float temporarily but the foil will eventually lose gas over time.

What size are the balloons?

Each letter balloon measures 16 inches tall. The width varies by letter shape, but the height is consistent for a uniform look when displayed together.

Does the set come with anything besides balloons?

Yes, the package includes one straw for inflation and two curling ribbons. You may want additional ribbons or string if your banner is long.
