Most issues of Gundam Ace contain at least one 'free gift' item. These may be used to promote a current Gundam work or based on original manga appearing in the magazine. In the three months leading up to the premiere of Mobile Suit Gundam 00, the magazine gave away a 00 pencil board, sticker sheet and poster. A continuing series has been keychains depicting Mobile Suit Gundam characters as chickens, based on a popular manga of the same concept. Other items given away include CM collection CD-ROMs, exclusive alternate manga cover sleeves and cardboard calendar cubes.
