I wear these socks daily. They truly don’t show with my workout shoes or with hey dudes. But the best thing about them is that they actually stay on your foot. I work out hard and I don’t ever have to pull them up. I do wish they were just a little bit thicker than they are, but they are definitely a product I will buy again.

Good value & taste.

Flavor Name: Variety, Size: 0.92 Ounce (Pack of 20)

I've bought these beef sticks several times & they're great. I'm not particularly fond of teriyaki flavor so I'll go back to the original. They're a good snack with cheese.

Bought this for my company's office for employees that work on-site. Let's just say they were GONE within 2 weeks. They were yummy!
