Wilson EZ Court Lines are the premier temporary court line solution! Perfect for locations without permanent paint or Court Line Tape, they stay in place on hard surfaces like gym floors. The vinyl is made to be highlighter yellow, smooth on one side and bumpy on the other. The bumpy side is meant to lay down and grip the floor. Each package comes with 12 lines and 4 corners, each measuring 13-1/2” long and 2-7/8” wide. Create a court with just the bare bones - two lines for each boundary, a line for the kitchen on each side of the net, a line for the service center, and the 4 corners. Setting up a game is a breeze with EZ Court Lines - no hassle and no mess!
