Simply Defined card bases
I have been using these card bases for a couple of years. I have other bases Sometimes the colors are off and sometimes they’re flimsy.
I always find myself reaching for these cards bases the most. I keep a stock at home of both sizes. They are sturdy and are a true white. Not the off-white you get when you read the package and it says white. I highly recommend this if you want a sturdy and true white card base.
