At Third Eye, we ship thousands of comics every week, and we know condition matters. Whether you're reading, collecting, or grading, we want you to feel confident when a Third Eye package arrives.
This policy outlines our standard for new release and shipped comics, and the industry-standard guidelines we follow.
OUR STANDARD
Books without a stated grade will be offered as Near Mint 9.4 or better. We do not guarantee 9.8 condition on any book unless specifically noted.
We use industry-standard grading guidelines from:
- CBCS Comic Grading Scale
- Overstreet Comic Grading Standards
- CGC grading standards
If you're new to comic grading, the resources above are a great place to start.
WHY WE DON'T GUARANTEE 9.8
Modern comic printing is an imperfect process. Books are printed in massive
runs, bound at high speed, and shipped in bulk to retailers. Even brand
new books off the truck will exhibit minor production characteristics,
and that's normal, and consistent with industry standards across every
retailer.
A 9.8 grade represents near-perfection, and the reality is that not every printed book qualifies for that grade no matter where you buy it from.
We can absolutely commit to NM 9.4 or better. We cannot commit to 9.8 on every book, because that's not how comics are made.
WHAT QUALIFIES AS NM 9.4
Per industry standards, a book may exhibit the following minor characteristics and still grade as Near Mint 9.4, as long as there's no accumulation of defects:
Bindery characteristics:
- Minor to moderate corner tears
- White edges along the spine (common on most modern printings)
- Covers slightly offset from interior pages (common on cardstock covers)
Printing characteristics:
- Slight color rub on back covers
- Small paper wrinkles present from the paper roll prior to printing
- Wavy paper texture from the printing process
Spine characteristics:
- 2-3 small color-breaking spine ticks
- Minor non-color-breaking spine dings
These are normal modern production characteristics, not damage from handling or shipping. They are present on books across the industry, regardless
of retailer.
OUR RETURN & EXCHANGE POLICY
We do not accept returns or exchanges on books that meet our NM 9.4 or better standard.
We will replace or refund:
- Books damaged during shipping (clear shipping damage, not pre-existing print characteristics)
- Books that fall below NM 9.4 standard (significant spine damage, major creasing, tears, etc.)
- Wrong cover or wrong issue shipped
For premium variants (1:25, 1:50, 1:100, 1:250, 1:500 incentive covers, signed editions, exclusive variants), we apply enhanced QC during pull and packing. If a premium variant arrives outside our standard, contact us within 7 days of delivery and we will work with you on a replacement.
