Card collectors and sellers, this Hobby Armor 200-pack of shipping protectors is exactly what you need for safe card shipping! Each protector measures 3.5x4.5 inches with rounded corners that slide easily into bubble mailers without catching. They're designed to hold toploaders, cards in penny sleeves, or even raw cards, providing that extra layer of protection against dings and damage during transit. The vibrant multi-color printing looks professional and will definitely impress your customers when they receive their cards. Made from lightweight corrugated cardboard that only weighs 0.18 ounces each, so they don't add significant shipping costs. They fit perfectly in #000 or larger bubble mailers, and having 200 means you're set for multiple shipments without constantly reordering. The quality is solid - these aren't flimsy like some cheap alternatives but provide genuine protection that gives you peace of mind when shipping valuable cards. Whether you're breaking sports cards, selling TCG singles, or trading with other collectors, these protectors ensure your cards arrive in the same condition they left. The designers are actually card collectors themselves, so they understand exactly what protection we need in the hobby. The value for a 200-count box is fantastic compared to buying smaller quantities, and they store flat until you need them. If you ship cards regularly or want to step up your trading game with professional-looking packaging, these Hobby Armor protectors deliver reliable performance that shows you care about your cards and your customers' experience.
