Frequently asked questions
Buying from Estudios Ninja
Do you have a physical store?
No, we are an online-only store. That is why every product comes with photos, videos and a detailed description, so you can get to know the book before you buy it. If you still have questions, our team will help you decide on WhatsApp.
Who are you? Do you publish other authors?
We publish our own titles, but we do not publish other authors. Most of the pop-up books in our catalog are not produced by us: we curate them and select them one by one.
How do I buy from another country?
- Add the books to your cart.
- At the bottom of the page, check that your country of residence is selected. This is key for international orders.
- Start checkout and fill in your details, including your postal code.
- If your country is selected correctly, you will see the payment and shipping options available for your country.
We ship worldwide.
Why am I seeing prices in Argentine pesos?
You are probably looking at the Argentine version of the store. Select your country at the bottom of the page to see prices in your currency.
Which currency are the prices shown in?
In US dollars (USD) for almost every country. In Spain prices are shown in euros (EUR) and in Brazil in Brazilian reais (BRL).
Which languages is the website available in?
Spanish, English and Portuguese. The language of the website is independent from the language of each book (see "The books" below).
Payment and shipping
How do I pay from outside Argentina?
With PayPal, either with the balance in your PayPal account or with any international credit or debit card. You are charged in US dollars, and your card's bank converts the amount to your local currency.
How do you ship internationally?
Only with DHL. We chose it because it is the most reliable, safe and fast option.
How long does international shipping take?
Approximately 5 to 7 business days for books that are in stock. Pre-orders take longer (see "The books" below).
How much does shipping cost?
The cost is calculated on the product page or in your cart.
Will I have to pay customs duties or import taxes?
Books are tax-free, so no duties or import taxes should be charged at your destination.
The books
What is the difference between in stock and pre-order?
Every book is either in stock or on pre-order. In stock means the book is already in our warehouse and shipping is handled automatically. A pre-order is a book that has not reached our warehouse yet.
How long does a pre-order take?
From the moment you buy, between 5 and 30 business days go by, depending on the title. That is the time it takes the book to arrive in Argentina. Once it arrives, we ship it and the regular shipping times start, depending on where you live. For details about a specific pre-order, write to us on WhatsApp.
Which language are the books in?
It depends on each title, and it is not the same as the language of the website. Most books are available in English and Spanish, but some exist only in English, others only in French and others only in Spanish, and some have editions in more than one of those three languages. Sometimes publishers release only certain editions in English, so there is no Spanish version. Whenever a Spanish edition exists, we also offer it in our catalog. To ask about a specific title, write to us on WhatsApp.
The book I am looking for is not in the store
You can suggest it and we will make a note of it. For a quick answer, write to us on WhatsApp.
Can I exchange or return a book?
Yes. Exchanges and returns are accepted within 30 business days, as long as the book is in good condition. Write to us on WhatsApp and we will take care of the exchange or return.
My book arrived damaged or was not what I expected
Write to us on WhatsApp. If the book arrived in poor condition, we will handle the exchange or return with no problem.
Do you sell wholesale?
We only sell our own titles wholesale. To ask about it, write to us on WhatsApp.
