## Customer Reviews

### ⭐⭐⭐⭐⭐ Flags for dog training
*by M***N on September 9, 2025*

Good and delivery was quick

### ⭐⭐⭐⭐⭐ Great price
*by J***I on October 20, 2023*

These flags are perfect height to stake in my yard. Reasonable price and durable.

### ⭐⭐⭐ Good enough for a weeks worth of service
*by M***N on July 16, 2018*

Nice amount of flags, we used them for the new dog fencing. The metal "pole" was very flimsy and rusted after two weeks of rain and sun. Also the flags are not blank white there is a logo printed on each flag.
