TNZMART 9 Inch Spot Markers Multicolor Number Football Yard Markers Anti-Slip Floor Spot Markers for Soccer Training

Good size for my needs. (Obstacle courses and the ground is lava) However, after having them outside with us in the sun during our first use, a couple numbers transferred onto one another and a blue one “shrank/warped”. Rather disappointing as I planned to use them outside quite a bit. Annoying to have to worry about sun damage in just a couple hours.

These were perfect for our cake walk! Made life so much easier!
