Do they come with the white mailer boxes?
depends on the seller
All Mattel items sold by GBFans.com are brand new in the box.
Sorry my bad I thought he meant sellers here on GBFans.
As somebody said before. It really does depend on the seller. Ask the question before sending your money. Do also bare in mind that some of the early figures weren’t sent in mailers by Mattel. The first Ray for example never came in a white mailer.
