Expert e-INK PRICING SOLUTIONS

Cardstock replaces the paper price sticker with a crisp 2.9" three-color e-ink display that docks to any standard graded slab. Each tag shows the card, the grade, and the price — in the same red-black-and-white look collectors already trust on a grading label.

When the market moves, you don't reach for a pen and a fresh roll of stickers. You open your phone, push the new price, and every tag in your showcase updates in seconds over a secure wireless link. The e-ink display holds its image without drawing power, so a single battery lasts through months of shows — and your prices are always as current as the market.

How it works:

1. Dock it. The Cardstock unit clips to the base of any standard slab. No adhesive, no residue, no risk to the holder.
2. Load it. Enter the card, grade, cert number, and price from the Cardstock app — one card or your whole inventory.
3. Update it. Comps moved overnight? Push new prices to one tag, a table, or the entire case at once. The display refreshes in seconds and holds the price with zero power draw.
