What We Actually Use: Our Full Kit

Scanning & cataloging

Ricoh/Fujitsu fi-8170 scanner (paid link), the document scanner every card gets digitized on. Full review and why a document scanner beats a "card scanner" in the fi-8170 review.
CardUploader (referral link), a paid part of our image-to-listing workflow alongside our own inventory tools. What it speeds up and what we still review, in how we use CardUploader.
SortSwift, inventory management and the pick-list system behind pulling and packing orders fast. Not a monetized link on our end, we just use it.

Numbered sorting tray (paid link), the physical system behind picking orders without hunting through boxes card by card.
Card dividers (paid link), for keeping listed inventory separated by batch or set inside a storage box.

Toploaders (paid link), thin toploaders for single valuable cards going out solo. Brand comparison in best toploaders.
Card Saver 1 semi-rigid holders (paid link), the cheaper, more flexible alternative for cards that don't need full toploader rigidity. What the difference actually is in semi-rigid holders explained.
Penny sleeves (paid link), the first layer on almost everything before it goes in a toploader or team bag. Sleeve comparison in best sleeves.

Team bags (paid link), the multi-card carrier that gets taped to the packing slip on almost every order. Sizing guide in best team bags.
Windowed envelopes (paid link), the plain white envelope behind almost every cheap bulk order. How to fit 30-plus cards in one in the cheapest way to ship bulk.
Bubble mailers (paid link), for anything that needs more structure than an envelope or crosses the weight where tracking is required.
Self-inking return address stamp (paid link), faster than a label for every outgoing envelope.
Thermal label printer (paid link), no ink, no per-label cost, prints a shipping label in seconds.
Packing tape (paid link), for sealing boxes and reinforcing the one corner that always fails first on a flat rate box.
Bubble wrap (paid link), layered top and bottom on any box shipping a large lot of bulk.
