From the Cotswold FAQ page:
Are your products brand new and genuine?
Yes, we only sell brand-new, genuine products. Our products are sourced globally and are fully compatible for UK use, including 3-pin UK plugs and English manuals where applicable.
Why is the box sometimes opened before shipping?
We take product quality seriously. That’s why we may open the box to carefully inspect and test the item before it’s sent out. This ensures everything is in perfect working order and matches exactly what you ordered. Rest assured, we only sell brand-new and genuine products.
