had the product of interest in stcok and avilable for quick shipment

Gracias recibido el pedido en tiempo y buen estado la mercancía

Good if it arrives as promised

So the low stars because, I received the products in two different boxes, which there didn't seem to be any reason as they would have fit in one. The order didn't indicate that there were two different boxes and they showed up days apart. I then contacted you via customer support being worried and no one reached out.

Thank you fast service
