On each article page, we provide you advice on how to make the best choice in terms of sizing according to the model. We recommend that you follow these tips. We also recommend you to check your size with this file. It is really important to print it at 100% (in your print settings) to be sure to have the right measure once it is printed.
To check if it well printed, you have the scale, and you have to check if the measure is exactly 5cm (and not 4.9 cm or 5.1 cm). If it is well 5 cm the size guide is correct and you can use it to check your size. If you have any doubt, do not hesitate to send us an email to email@example.com.
