HANDY FAQs

What is ONU’s policy on authenticity?

We only stock 100% authentic products guaranteed or your money back.

We know that authenticity is the essence of luxury. That's why with us, you can always be confident that you are purchasing a genuine luxury item. We take the authentication process very seriously and value your loyalty and trust.We are aware of scam websites selling fake products, replicas and imitations, but rest assured, we are not one of them. We do not sell counterfeit products, grey markets or second-hand goods. As a registered UK company, this statement is legally binding. For extra peace of mind, we have a 30 day guaranteed money back returns policy for all unworn items with tags/security ribbon attached. For more information visit our Delivery & Returns page.

What is ONU’s relationship with official distributors?

So, who are we? ONU is a family-run business that has been trading for over 25 years and selling luxury menswear online since 2018. All our items are 100% genuine, brand new with tags and original packaging. We source only from official authorised distributors and stockists and do not dropship or outsource. Everything you see on our website is stocked/owned by us and physically held in our warehouse and store.Most items now have Certilogo labels, RFID or authenticity certificates supplied with the products and can easily be checked for authenticity online. Please note this is dependent on the brand and year of manufacture. Read more about this extra layer of security and how to check your own product below.

What is RFID and what does it stand for?

RFID stands for Radio-Frequency Identification and is a type of tracking system. To help fight fakes, numerous retailers including, Gucci and Moncler, have implemented this system. The tags use radio frequency to identify and communicate with items and people. They can store a range of information and are a simple way to ensure your product is authentic.

How can I check the authenticity of my product?

Many of your favourite luxury brands like Stone Island and CP Company use Certilogo to authenticate their products. Please note whilst Certilogo's cannot be copied, it is best not to share your unique code or number with anyone.Checking your product couldn't be easier! Scan the QR code on the label with your smartphone; this will open the Certilogo website. Answer a few simple questions regarding the purchase of your item. Then from your answers, Certilogo will determine the authenticity of your item.
