I forgot I had this Hello Kitty set stored in my basement in a bin.  It has been many years.  It is brand new from a sample sale in NYC.  
But there are some scratches on the pieces.  Please look at the pictures.

And on the tissue box, there seem to be a remnant of tape.  It is not sticky but if you hold it in a certain light, you can see it.
Otherwise, it is not noticeable.  Please look at the last picture.  I tried my best to take the picture from an angle. 

Also the white color has tarnished to a cream color.  Please take a look at the pictures.

It is all new, but old.
