Registered Labels

I am not really into collecting registered labels of Malaysia. However, these registered labels are quite attractive. If not mistaken, there are altogether six types of registered labels in Malaysia. I show here only five types - red, blue, green, brown and yellow. The other one type I do not show here is a pink colour one. The red label is for domestic registered mail; the blue label is for international registered mail; the green label is for postal service registered mail; the brown label is for registered mail delivering traffic summons; and the yellow label is for domestic AR registered mail. On the other hand, the pink label (not shown here) is for international incoming registered mail.
