The product is good, but the sale was misleading

I bought a package of boxers to be sent to Canada, I was always aware of the high price of shipping and I agreed, but I expected to receive a package of 3 units for $30 dollars, not just an individual boxer, the receipt of a Only boxer discouraged me.

My intention was to support a Ukrainian company at this time, but I also don't like to feel like my good will is being abused.

Best underwear yet!

I've been wearing Man's Set for 3 years now. I won't wear anything else. The tag is scratchy and the new style fly being tilted to the right, I don't like. Other than that... The complete separate pouch for the "set", absolutely the BEST!

I love your underwear, however, I didn't get red, it was purple.

They sent the wrong color.

I ordered blue. They sent black. Love the product but no response when I alerted them to the mistake. But, other than that issue, I strongly recommend.
