My kids aged 4 and 7 use as football goals, for dribbling drills and turning them into hurdles using garden canes using the groves on top of cones. (You can also buy hurdle markers)
Bright and stable
I bought these cones to replace some old ones a few weeks ago, the first comment I got was from my young team stating how good they looked and the parent also commented on how profession these cones look. I will be purchasing more as the team grows, time to throw away the standard cones you can get and buy these!
