These are my Premium Nintendo 64 cases! Gone are the days of utilizing the cheap, clear, universal cases for N64 games. These hard black plastic clamshells hold manuals AND memory cards, and have clips to keep the carts secured in place. The dimensions match my S/NES cases. Just insert the name of a game for each case you have in your cart during the checkout process in the buyer's note section, and feel free to contact me ahead of time to get samples and work out specifics. These items are made to order and I work a day job, fulfillment can take up to 30 days from time of order (it shouldn't be anywhere near this realistically). Listing is 1 item per order. No returns available because these are made to order. Thanks for looking!
