Review on 🎾 Franklin Sports Pickleball Court Marker Kit - Official Size Court Throw Down Markers with Tape Measure - Pickleball Court Lines Marking Set by Nelson Calafell

Purchased as indoor boundary markers, primarily to be laid on a hardwood gym floor. I figured it would be a thinner rubber like a strong sticker so they stick to the wood floor and don't get in the way of the ball when the ball hits the marker. It's thick, durable rubber that isn't cut square, doesn't sit flush with the ground, and won't stay in place when stepped on. I sent them back quickly. Gave 5 stars for durability and strength because they are thick rubber. 5 stars for easy assembly as no assembly is required. Doesn't work for Pickleball in general.
