Class of 2026 Graduation Cap Foil Balloons – 2 Pack Large Black with Automatic Sealing

The Domgoge 2-pack of Class of 2026 graduation foil balloons features black Diploma Bachelor Cap designs in large size, made from durable, reusable polyester (Mylar) with an automatic sealing opening that eliminates the need for knots. These balloons are designed for air or helium inflation and come with tape for easy mounting.

What’s Inside the Pack

• 2 large black foil balloons shaped like graduation caps
• Roll of double-sided adhesive tape for sticking to walls, windows, or doors

How the Automatic Sealing Works

Each balloon has a special valve at the opening that seals itself once inflated. There is no need to tie a knot – just inflate and let go. The tail pulls tight to secure the seal. This saves time and makes setup much easier compared to traditional latex balloons.

Material and Reusability

The balloons are made of double-sided aluminum foil (Mylar), which is lightweight, non-toxic, and resistant to tearing. They can be deflated carefully and stored flat for reuse at future celebrations. Their durable construction helps them stay fully inflated for an extended period when properly sealed.

Ideas for Display

These balloons work well as part of a graduation party backdrop, hung from ceilings, taped to walls, or arranged along a dessert table. They pair nicely with other black-and-white or school-colored decorations. Use the included tape to attach them to almost any flat surface, or string them with ribbon through the top holes.

Important Care Tips

• Do not overinflate; fill with air or helium until firm but not stretched.
• Keep away from heat sources, sharp objects, and open flames.
• Due to monitor differences, actual color may vary slightly from photos.
• For helium inflation, inflate on the day of use – float time is typically 4–12 hours.
• Store in a drawer when not in use for later re-use.

Common Questions About This Set

Can I use a helium tank to inflate these?

Yes, these foil balloons support both air and helium. They will float only if filled with helium (smaller sizes may not float). Use caution with hydrogen – keep away from fire.

Are the balloons reusable?

Yes. Deflate by gently pressing the valve, fold carefully, and store flat. They can be re-inflated multiple times if handled with care.

What exactly comes in the package?

You receive two large graduate cap foil balloons and one roll of double-sided tape. No pump or helium is included.

Do I need to tie a knot after inflating?

No. The automatic sealing design secures the balloon without knots – just pull the tail tight and it seals itself.
