The piece is sealed and, therefore, brand new! The box comes with a leaflet and a numbered certificate of authenticity, here n°257. 
( We withdrew the candy in the red bag (produced 20 years ago) out of the box). 
I took pictures of one piece from another "Melting Dob / Nega" box ( 10 pieces in one big and black New York box ) so that it is easier to show the piece. 

The New York Edition is a 4 Figure set: Kaikai Kiki & Flower / Blue, Mr Dob & Mushrooms / Pink, Miss Ko2/ Clear, Melting Dob / Nega. Here it is Melting Dob Nega. 

The New York edition is the most sought-after edition, with only 3000 pieces. 

There have been 30000 pieces for the Konbini serie, 30000 for the Los Angeles edition(2004), 15000 for the Roppongi Hills edition, and 12500 for the Artelligent City edition. 

MR DOB is Takashi Murakami’s alter ego. Mr Dob is one of his most iconic works. If you're looking for an affordable OG collectible from Takashi Murakami, this box is a great place to start.
