Questions? Nika has answers!

Nika's books are PDF e-books. After purchase, you'll receive them instantly by email, so you can download them, open them on a computer, tablet or phone, and print them for personal use as many times as you need.

Yes. You can print the e-books for personal use as many times as you need, and a standard home printer works just fine. Print once and use forever, or print fresh pages whenever your child wants to color again.

Nika's books are mainly recommended for children aged 3–10. Younger children can enjoy them together with a parent, while older children often complete the activities and coloring pages independently.

After purchase, the e-books are automatically sent to the email address you provide. They usually arrive in your inbox within a few minutes after payment. Check your spam folder if you don't see them, and contact us if there's any issue.

First, check your spam or junk folder, since automated emails sometimes land there. If the e-book still hasn't arrived after 15 minutes, please contact us and we'll sort it out as quickly as possible.

All 20 titles are available in three language versions: Polish, English and Swedish. Every book in the collection is translated in full, not just some titles.

Yes. In the shop, you can use the language filter to choose books in Polish, English or Swedish. Bilingual bundles are also available for families who want to read and learn in two languages at once.

You can use a card, BLIK, Swish or bank transfer to complete your payment. Everything goes through Paddle's secure checkout, so your payment details stay protected and safe.

Because the e-books are digital products delivered immediately after purchase, refunds are not available once the file has been delivered. However, we want everything to work smoothly. If you don't receive your e-book, notice an error or have trouble downloading it, please contact us and we'll help as quickly as possible.

Yes! New titles are in development. Follow us on Instagram and Facebook to be the first to know when new books are released.

Sometimes the PDF preview in a browser may not open the file correctly. Don't worry, just download the e-book to your computer, tablet or phone and open it directly from your device. If the problem continues, contact us and we'll help.
