Frequently Asked Questions
Everything you need to know about First Class Card Pro, USPS ESE compliance, kit contents, patents, and return policy.
What is the eBay Standard Envelope (ESE)?
The eBay Standard Envelope is a USPS shipping option available exclusively through eBay for trading cards, coins, and small flat items. It offers significantly reduced shipping rates (as low as $0.68) but requires strict compliance with USPS automated sorting machinery dimensions: max 6"x9", max 0.25" thick, must be flexible/bendable.
How many cards can I ship per envelope?
With the First Class Card Pro system, you can safely ship up to 6 cards in a single ESE shipment while remaining within USPS thickness limits. This is a first in the industry — most DIY methods max out at 1-2 cards before exceeding the 0.25" threshold.
What comes in the Pro Kit?
The 100-Shipment Pro Kit includes: 100x Carrier Cards (18pt gloss cardstock), 100x Aimoh #10 Security Envelopes, 200x Penny Sleeves, 100x Top-Loaders, 250x Vinyl TL Seals, and 1x Glue Dots Dispenser (450ct). Everything you need for 100 professional shipments.
Is the system USPS compliant?
Yes, 100%. The Carrier Card dimensions, thickness, and flexibility are specifically engineered to pass through USPS automated sorting machinery without jamming or triggering manual processing surcharges. This dramatically reduces lost/delayed shipments.
What does "Patent Pending" mean for this product?
We have filed a utility patent application covering the Carrier Card design, the alignment guide system, and the overall integrated shipping method. This means First Class Card Pro is the only authorized provider of this specific technology.
Do you offer bulk or wholesale pricing?
Absolutely. We offer tiered pricing for orders of 500+ shipment kits, custom branding options for card shops, and enterprise fulfillment contracts. Visit our Bulk & Commercial section or contact us directly for a custom quote.
How long does it take to pack one shipment?
With the Pro Kit system, an experienced user can prepare a single-card shipment in approximately 30-45 seconds. Multi-card shipments (2-6 cards) take about 60-90 seconds. Compare this to 3-5 minutes for traditional DIY tape-and-cardboard methods.
Can I use my own envelopes or top-loaders?
While our kit components are specifically tested together for optimal results, the Carrier Cards work with any standard #10 envelope and standard 3"x4" top-loaders. However, we recommend our tested Aimoh envelopes for guaranteed seal strength and opacity.
What is your return/refund policy?
We offer a 30-day satisfaction guarantee. If you're not completely satisfied with the Pro Kit system, return any unused components for a full refund. Used carrier cards and opened consumables are non-refundable, but we'll work with you to resolve any issues.
Do you ship internationally?
Currently, we ship within the United States only. The Pro Kit is designed specifically for USPS ESE compliance. We are exploring international shipping options and partnerships for 2024.
