Postal test,no security sticker

[ImFree2doasiwant]

Shall I nit bother posting it? It has a smaller piece of sticker, but not the correct security one. Just wondering if it'll be "void" and if its best to just get another test.

I had this recently and sent it with the sticker there was. It was processed with no issues

I had that, called the helpline and they said to use a bit of tape. It was processed fine.

Oh great! That's a relief, thank you

I called the helpline they said it had to be the official sticker or they’d refuse to process it.
