They work together. A penny sleeve is a thin, soft plastic sleeve that guards the card's surface from scratches and fingerprints — cheap (hence the name) and used as the first layer. A top-loader is a rigid plastic holder that protects against bending and impact. Standard practice is to put the card in a penny sleeve first, then slide the sleeved card into a top-loader, so the hard holder never rubs the card directly. For more protection, semi-rigid holders (for grading submissions) and one-touch magnetic cases (for display) are options. Basic sleeves and top-loaders are inexpensive and worth using on any card you care about. Most card shops stock supplies.
