After 10 days, I received this morning my order in my mail.
I've examined the boxes, and apart that the SIAC's box plastic base was a bit worn off, they shipped in mint condition.
Just trying to figure out if they are counterfeits: I've ordered them from a retailer in the UK. The SIAC's box says Made in Europe with the EU flag and the STU's box has both the US and EU flags and says Printed in Spain. I know that the company's offices are in Spain, so I guess that's right.
Any other tips on how I can determine the genuinity of my products?
Good day to you!
