Terrible product, glue spots on cheaply made flags
The flags are made carelessly and look incredibly cheap. Every single flag has yellow glue spots all over the white part making them look terrible. Most of them were stuck together upon opening. The metal handle has some form of black, sticky, oily dirt on it which got all over my hands. I had to wipe down every flag and even then couldn't get them very clean. (The picture I posted was the residue of wiping one flag on a damp paper towel) The sticks also bend with very little pressure so if you're using them to mark outside, they will not hold or last. Just a poorly made, thoughtless product.Save your time and money and buy elsewhere.

Blindingly bright
I absolutely love these markers! I use them to mark where my dog’s go outside. I have 3 colors and use them for different things. Yellow is the brightest and best. No matter what is on the ground you can’t miss them. My neighbor used some of mine and loves them so I’ll have to get more. Very affordable. Worth every penny.

value, quality all there.
We are on 5 acres and have underground electronic fencing for our dogs. With an 8 week old puppy on the way fence training was in order. I needed to pin three sides of our front yard after reading several product reviews I settled on this product. It arrived in quickly with the Amazon Prime. The box was damaged, but the product was not, packaged nicely. Other reviewers both for this and other flags mentioned product loss due to flags sticking. I ordered two bundles of 100 and not one flag was damaged, or stuck together. Pink really stands out nicely against the green and does make a visual fence, and the 21" length allows for enough depth to sink below grade while having enough above grade. very happy would buy again.

Good purchase, worked well
So I definitely didn't need 100 of these things, but the other quantity options weren't enough either, and for the price, I got 100. Why not. I got these to mark the land mines of dog poop in our yard as I cut the grass so my husband could pick them up when I was done cutting the grass. Hahaha, yes, that is what I bought them for, for real.They work great, they slide into the grass, no problem. The white definitely stands out against the grass very easily, no matter how far out in the yard they are.The only downside, is the Steel Wire Staffs rusted super quickly. Anytime I grab a handful and plant them in the yard when I mow, I have rust EVERYWHERE all over my hands and any other place they accidently touched or brushed up against.We keep them stored outside in our shed, so that might be why they rusted. I reccomend keeping them stored inside if you don't want them rusting, and keep them out of the rain.

Great color
Using these to plant many flowers like color of the flags. I am using all different colors, so I know what I am planting next to what color. Using red, pink, orange, blue, purple, white flags etc. to color coordinate plantings hundreds of flowers. Few came off in high winds.

Genius idea, not durable for my use
On a 5-acre property it's hard to keep track of where my golden retriever makes his mess, so to speak... needless to say I was ecstatic when I came across this genius product!!! I've told many people who come over about these flags, because sometimes our yard looks like a mini golf area... But was very disappointed when they're rusted extremely quickly and snapped in half

Swanson FG421100 4-Inch by 5-Inch Marking Flags with 21-Inch Wire Staffs, 100 Pack, Green
As per another review on this product I already read, the color of the received product was different than what was pictured when I ordered. The received marking flags were a much darker green, not the bright green I was looking for and was shown in the picture. I am using the ones I received, even though the color did not meet my expectations. They are holding up fine so far in windy Wyoming.
