Tonga's flag is the only national flag in the world that is written into its constitution as unchangeable. Red field, white canton in the upper hoist, red cross inside the canton — adopted 4 November 1875 under King George Tupou I, and untouched since. That fixed geometry is also why this flag is harder to print correctly than it looks, and why the cheap versions you see online are usually wrong.
We screen print it on 100D polyester with a white canvas hoist and two brass grommets. MOQ 100 pieces, seven days.
