This listing is for both! You will receive the 16 and 24oz tumblers. These have never been used. Still have their bottom and straw stickers! Super fun! Great for any evening adventures or movie theater, etc fun you might have planned! Please see pics as part of the tumbler descriptions and conditions. I have sent many of these tumblers so I will be sure to pack in such a way that they arrive safe and sound! These will be coming from a smoke free and pet friendly home!!
