ModRetro Chromatic Codex Edition Price & Resale (Nov 10)

What's worth a look today? The ModRetro Chromatic: Codex Edition, a $200 handheld sold on OpenAI's Supply Co. store. It sold out on release day, and the product page now says "Restock soon, expected restock: November 19." Our team said before the drop that it planned to grab a few. Below: the retail price, the eBay sold range as of November 10, how rare it is, the return policy, and a smaller second pick from Mattel Creations.

How much is the ModRetro Chromatic: Codex Edition?

The OpenAI Supply Co. page lists it at $200.00, and it includes one programmable game cartridge. Per the same page, it ships only to the US, Canada, Australia, New Zealand, Japan, the UK and the EU. The store says it was first introduced as a DevDay exclusive and is now back "with a new look" as a Supply Co. drop.

Our team said the per-order limit was 10. We didn't see that limit on the page ourselves, so treat it as the team's report. The team also noted that ModRetro's regular Chromatic models are about $149.99 and that the limited DevDay version has sold for far more on eBay, which is why they expected the $200 price to leave room.

Is the Codex Edition sold out? Restock date

Yes. Stock flickered between sold out and back in stock on release day and then ran out. The product page now shows "Restock soon" with an expected restock of November 19. A restock is the biggest risk to resale prices, because more supply usually means lower prices. The team's own caution was that nobody outside the company knows how many were made.

How rare is the Codex Edition?

We couldn't find a published number for this Supply Co. release. Many eBay listings say "1 of 2,500", but that wording refers to the earlier DevDay giveaway edition, comes from sellers, and is not an official figure for the $200 version. Our team pointed out that some people assumed the new release was capped at 2,500 and that nothing confirmed it.

ModRetro Chromatic Codex Edition resale value on eBay

We checked eBay on November 10, 2026, looking at sold listings only. Prices depend a lot on which version was sold:

• Earlier DevDay "1 of 2,500" edition: sold from about $500 up to $1,750 between September 29 and November 7, with most between roughly $700 and $1,300. Recent examples include $700 (open box, Nov 7), $950 (open box, Nov 3) and $900 (new, Nov 3).
• New $200 release: one sold listing, a new sealed "Codex Edition - 2026 OpenAI Clear Edition", sold for $395 on November 9, with free delivery. We can't tell from the listing whether it was a DevDay or a Supply Co. unit, so don't treat one sale as a trend.
• Comparison, the Anduril Chromatic: our team bought those at $350. Sold prices in the last two weeks ran about $445 to $655 on eBay, and $575 on November 9.

The team's pre-launch guess was $350 or more, with a range from about $300 to over $500 depending on supply and how many resellers buy. That was a guess, not a promise. With a November 19 restock coming, expect the first-day prices to soften.

The math: $200 retail versus resale

At $200 plus any shipping, a $395 sale is about $195 of gross room, and eBay's fees and your shipping come out of that. You'd also be racing a restock. At $300 the room shrinks quickly. Because the item can't be returned (see below), the only exit is selling it.

Can you cancel or return it?

OpenAI's Supply Co. FAQ says that due to limited availability it cannot accept returns or exchanges for non-defective items, and that all sales are final unless an order arrives damaged, defective or incorrect. Shipping fees, duties, taxes and import charges are generally non-refundable. ModRetro handles support and warranty for the device. We did not find a cancellation policy on the page, so don't assume you can cancel.

Flip, hold or pass? Our take

Hold, small and careful. The team called these "super cool" and planned to buy a few, but also said the unknown supply scared them. A sold-out first day plus a restock date of November 19 is a classic setup for prices to peak early. If you didn't get one, waiting for the restock at $200 is reasonable. This is not a guaranteed profit, and the all-sales-final policy means the risk is yours.

Second pick: Monster High Skullector "Us" Adelaide and Red 2-Pack price

Mattel Creations has the Monster High Skullector Us Dolls, Adelaide and Red 2-Pack at $40.00, marked down from $100.00 (60% off), and the page showed it in stock when we read it on November 10. The page also lists an extra 20% for members and double points, as part of its "Merry Markdowns" sale. Our team's note: one of the weaker-selling Skullectors, but at this price it's cheap to hold.

• Team's resale estimate: about $90, with a warning it will likely drop.
• eBay sold (checked Nov 10, 2026): $60 to $91.95 over November 2 to 8, including $91.95 (Nov 8), $90 (Nov 6) and $60 twice (Nov 4 and 6, best offer, plus shipping).
• Returns: Mattel Creations accepts returns within 30 days of receipt for a refund (minus shipping and processing) or exchange, if the item is in the condition received and in the complete original packaging. Orders shipped to international addresses are not eligible. We did not verify a cancellation policy.

Our take: hold. Resale looks healthy now, but a sale can push more supply onto eBay. Keep the box sealed and don't expect a guaranteed profit.
