Pythagorean offers print-on-demand (POD) products, so our products are produced and shipped from many countries, since we only work with the most important POD companies in the world, and they have a worldwide presence.

We accept payments with Visa, Mastercard and Amex cards through Paypal, however it is not necessary to have a Paypal account to access this payment method. We also accept payments through Paypal accounts. Additionally, we accept instant payments with USDT cryptocurrency through a payment gateway.

Our products are printed on demand, so you have to add the printing time to the processing times of each order, which is usually 2 or 3 days, but it may vary depending on the amount of work of the printing establishment closest to your location.

Print-on-Demand is a service in which the products are printed as soon as an order is made, that is, once the customer buys it.

When you buy print-on-demand products you are saving on shipping costs, since, thanks to this service, your product can be shipped from an establishment closer to your location.

You are also helping the environment because, unlike mass production, on-demand production does not generate waste.

Lastly, you are supporting ventures that improve the market offer with different and extraordinary products. Without on-demand production services, there would be no brands like Pythagorean which is aimed at a very specific audience, and whose mass production is not economically profitable.

The quality of POD products depends on the POD service you work with. There are many POD services around the world, however,  we have a policy of working only with the highest quality services. The quality of our  products is equal or superior to  any renowned brand.

Once your order is verified and approved to apply for a return, we will indicate an address (local or foreign address, depending on your country) to send the item. If the reason for the return is related to a mistake made by us, then we will bear the shipping costs. We do not accept returns for size changes. For more information you can read our return and refund policy

During the checkout, choose the USDT option, the system will indicate the payment address from your wallet, and the payment will be credited immediately. If you have any questions please contact us.
