Mail labels from New Zealand

Today when I open my mail box, I saw a letter from New Zealand. So surprise as never been informed that will be a letter sent to me before. So curious about this. So quickly bring to room and open the letter. Can you guess what is inside the letter?
Haha.. I am so happy with that. It is mail labels from New Zealand. Not only one type of labels, but many different type of mail labels. That really make me so happy.
I had been try to ask around to get the labels from New Zealand before, but the answer normally is not using or can't get it. Really a bit disappointed after that.
But who knows, today so lucky I can have all the mail labels from New Zealand.
Really give me a hope that this world still got kind and helpful people will come and help you.
Thanks to Fran and also all the friends helping me before with my mail labels collection.
Thank you very much!!
