On The Wall Happy 21st Birthday bunting, black and white, 4m, 10 flags

Set the scene for a milestone celebration with the On The Wall Happy 21st Birthday black and white bunting. These bold flags add clean contrast and help you build a simple photo backdrop for friends and family. Hang the bunting on a wall, across a doorway, over a table, or along a staircase for fast party styling.
The banner is pre-strung, so there is no assembly. It measures 4 metres long and includes 10 flags, giving wide coverage in one line, a gentle curve, or split across two areas. Use it behind a cake table, on a drinks station, or as an entrance sign to guide guests in.
Durable card flags hold their shape during the event and keep the numbers easy to read in photos. After the celebration, fold the bunting flat for tidy storage, then reuse it for future birthdays, or recycle the card when you are done.
Pack sizes: 1, 2, 3, 4, or 5. Use indoors or outdoors for home parties, halls, and garden celebrations.
