CUSTOMS AND BROKERAGE FEES, DUTIES, AND TAXES

For orders that are shipping to destinations outside of the United States (including Canada), you may have to pay duties and taxes to your country's government. This is because you are importing goods from a foreign country into your own country.

C-IN2 does not estimate nor collect these duties and taxes on your behalf. Please contact your country's customs office to obtain an estimate of the duties and taxes, if any, you will have to pay.

We cannot and will not alter, falsify, or in any other way misrepresent or undervalue the declared value of an international shipment. The full amount of the purchased items will be noted on the customs declaration.

In addition to duties and taxes, you may have to pay an additional brokerage fee to either your country's postal system (if your order ships via our International Standard or International Standard Plus shipping methods) or to FedEx (if your order ships via our International Economy and International Priority shipping methods). This fee, which is not estimated nor collected by C-IN2 on your behalf, covers the carrier's cost of expediting the clearance of your shipment through your country's customs process. A typical brokerage fee averages USD 10.00 - 20.00. Check with your local postal office to estimate any brokerage fees, if any, you will have to pay.

If you do not pay duties, taxes, or brokerage fees, then in many cases the parcel will be destroyed by your country's customs office and not sent back to us. In such cases, we will not issue a refund. We can only issue refunds for parcels that are returned to us.

Great boxers!

It’s hard to find a boxer that’s comfortable AND doesn’t look like you are wearing a ton of fabric...these are the perfect ones! They look amazing on and are very comfortable.

The best of both worlds

I'm somewhat old fashioned in my choice for woven boxer shorts most of the time, but sometimes I like the shorter length, tighter fit and trimmer dimensions of knit boxer briefs. The core runner boxer is the best of both worlds because the fabric is loose enough to resemble traditional boxers but brief enough to achieve a desirable fit. What's not to like?

The best boxer shorts ever

I ordered more right after I received the first delivery and tried them on. These are the best boxers I have ever had - I think ideal for everyday wear!

Relaxing fit the way you like it.

Like this runner boxer, material is comfortable and soft. Prefer to wear it at home.
