GemmaCards (gemma.cards) sells digital booster packs of real Pokémon and One Piece sets. You open them with coins, and every card you pull is yours: keep it in your binder, trade it back to Gemma for coins, or have it shipped, in which case Gemma sends it from its own stock or buys that card on the open market for you. It is run by Gemma Media SRL, a company in Prato, Italy.
There are 42 sets, 22 Pokémon and 20 One Piece, from One Piece's first set, Romance Dawn, to Pokémon's 30th Celebration. Most packs cost 500 coins, which is €5; seven premium sets cost 1,000. Coins are store credit: you buy them by card, and they never turn back into money.
Each set's pack page shows how often packs opened on Gemma have landed in three value bands, and Gemma says its packs are calibrated to return about 80% of the pack price in card value on average (its FAQ says the premium sets hold less). That is its own figure, the same on every pack page, and there is no record of pulls for us to measure it against, so this page reports their numbers rather than a return of our own.
Our verdict
Real sets opened from your phone, with every pack locked by a hash before you pay and a plain price list for shipping the cards you keep. Three things to know first. Coins never turn back into cash: apart from a top-up you haven't touched, refundable within 14 days, what you put in stays on Gemma. Trading a card back pays 90% only on cards under €2, falling to 75% from €10 up, and it is a share of the price Gemma puts on the card. And the terms cap the value of the cards a single pack can hold, without saying where the cap sits.
A Gemma pack is a digital booster of a real set: the cards in it are drawn at random from that set's card list, and each one you pull is a claim to the physical card. Nothing expires. A card sits in your account until you trade it back or ship it.
When you ship a card, Gemma sends it from its own stock if it has it, and otherwise buys that exact card on the open market for you. A card bought for you is the same version and number you pulled, listed as Near Mint by the supplier, and the terms say grading is not guaranteed unless a listing says otherwise. If a card can't be found at a reasonable price within a reasonable time, Gemma credits you its full market value in coins instead.
An opened pack is never refundable, whatever it held.
Each set's pull-rates panel shows how often packs opened on Gemma have landed in three bands of total card value: Base, under €4; Big Pull, €4 to €10; and Chase, €10 and up. Gemma calls these rates measured, not promised: they come from its own record of packs opened and refresh as more are opened. On 8 November, on the 1,000-coin 30th Celebration pack, about a quarter of packs had landed in Base, just over half in Big Pull and just under a quarter in Chase.
Under the bands, Gemma says the engine is calibrated to return on average about 80% of the pack cost in card value over time, and its FAQ says the double-price premium sets hold a smaller share than that. That is one figure for every pack, not a number per set.
Each set also carries a 1-to-5 lightning rating for how big its top end is, worked out from card prices rather than pull rates, and Gemma guarantees you never go more than 10 packs without a card worth at least €5. One thing the pack pages don't show: the terms say the value of the cards in a single pack is capped by Gemma's card-selection software, the same for every user, and the cap itself isn't published.
100 coins are €1. Coin bundles run from €9.99 for 1,000 coins to €499.99 for 60,000, the bigger ones with bonus coins, and a one-off Welcome Pack gives 3,500 coins for €24.99. New accounts start with 1,000 coins, two packs' worth. You pay by card through Stripe. A top-up you haven't touched at all can be refunded within 14 days; once any of it is spent, the rest can't be.
Trading a card back is instant and pays coins, at a rate set by the card's value: 90% under €2, 80% from €2 to €10, and 75% from €10 up. The home page quotes the 75%. The value it is a share of is the price Gemma puts on the card. Its FAQ calls that a list price that tracks live market data refreshed daily and includes its sourcing and shipping margin, so it sits above the bare Cardmarket price; its verification page calls it the card's Cardmarket price.
Shipping costs €10 for the first 3 cards, whatever they are worth, and €2.50 for each card after that. Each card worth more than €100 adds €5 and travels insured: if the parcel is lost or stolen, Gemma sends the same cards again. You pay it by card, not in coins, and shipping unlocks only after a first purchase of €10 in coins. Every parcel is tracked, and delivery usually takes 7 to 10 business days.
Gemma ships to every EU country, the United Kingdom and the United States. In the US the €10 covers 5 cards rather than 3, and once you have topped up more than €99.99 in total you get one free shipment of up to 3 cards every 30 days. UK addresses pay the same figures in pounds.
GemmaCards is run by Gemma Media SRL in Prato, Italy, and its terms are governed by Italian law, with EU consumers keeping the protections of their own country. You must be 18. Support is by email at [email protected] or on Telegram.
It suits you if you collect modern Pokémon or One Piece sets, like opening boosters, and want the cards you love posted to you in the EU, the UK or the US. It suits you less if you want to cash out, since coins never turn back into money.
Odds, packs and terms are GemmaCards's to change.
GemmaCards is run by Gemma Media SRL, an Italian company in Prato. Every pack is sealed with a SHA-256 commitment before you pay, and each card you pull can be shipped to you: Gemma sends it from stock or buys that card on the open market. Its terms and refund policy are published in full.
No. Coins are store credit with no cash value, and trading a card back pays coins, not money. The only refund is for a coin top-up you haven't used at all, within 14 days. What you can do is have your cards shipped.
€10 for the first 3 cards and €2.50 for each card after that, plus €5 for each card worth more than €100, which then travels insured. In the US the €10 covers 5 cards, and UK addresses pay the same figures in pounds.
