you dont need to understand the language, just to clikc on the black “ADD TO CART” button

also you can do right click and translate to english :slightly_smiling_face:

I tested the add to cart button. It works fine. Did you fix it? And nice website!

thank you :slightly_smiling_face:

i checked it and its a problem with my wi fi, i dont what it is but when i use 4g its working and then i switch to wi fi and its not working
