Nyko Blob Light Green Attachment Nintendo Game Boy Color & Game Boy Pocket NOS

Item is still sealed in original package. Old stock. Dated 2000. Nintendo collectible for game boy color - pocket system. Such a cool monster. I have two (sold separately) so packaging of sealed items may vary slightly. They do have shelf wear, blister dents, etc. No way of testing this vintage product. Selling as untested. Thanks for looking.
