On average, 4 standard paper sportscards, each in a penny sleeve, will fit in the sleeve. Chrome cards fit 2 comfortably. These are great to use with plain white envelopes (PWE) to take advantage of Ebay's Standard Envelope shipping. You can put 2 shields in a standard letter envelope, holding 2-4 cards each. The sleeves weigh next to nothing, and a single card inserted in there weighs only 0.3oz. You can ship 3 cards and stay under 1oz. If you have bought single cards from me in the past, then you know that this is what it came in. I have shipped thousands of cards like this and not once had an issue.
