Amazing but quality changed
Size: Large, Color: (002) Black / Black / Halo Gray
Love these socks so much, been buying them for about 4 years now!! Not giving them 5 stars anymore because the quality is different and not as good, durable and thick as before.

The best no show socks
The only no show socks I have ever found that do not slide down. These are very comfortable and the extra tab on the back provides comfort by keeping shoes from rubbing the back of your foot. The top of the sock also comes up high enough to cushion the top of your foot all while still remaining hidden while wearing tennis shoes or even with my hey dudes.

Great product and service after disappointment
Flavor Name: Traditional, Size: 4 Ounce (Pack of 1)
Ive tried a few different brands of biltong and made my own. I have to say that this wasn't my favorite. Believe me, i wanted to like it. The taste was sour and most of the bag was pulverized shreds. :( I did find that letting a bit airdry in a bowl made it a little more palatable, but honestly it'sjust sitting in my fridge still, where normally I'd have eaten the whole bag in a day or so. I will say that there was a decent amount for the price. The texture and cut were good on the whole pieces. Also, some of the bites left a weird coating and nasty taste on my tongue, like baking soda or something, but definitely an off taste.
I had my own beef jerky store for several years, so I'm a connoisseur, but no snob.
-----update 8/13/2019-------
I contacted customer service via the email on the bag and got a response. They sent me a new bag and here is the email I sent them back. Very happy now.
....The biltong showed up last Thursday! I'm sorry i kept forgetting to email you.
It is delicious. It's night and day difference between the bag I got through Amazon originally.
This bag was pristine and the taste is spot on. Every piece is a perfect slice, no shreds or fluff. Dark, rich brown color, not hay colored like the old bag. I really think that the other bag got very hot or something and out the taste off.
Thank you so much. Now I know that if I am in the mood for biltong, Ayoba-yo is a good choice.
Thanks for the customer service as well.....
