These clear adhesive mats are absolute game-changers for basketball players and anyone who needs better traction! Each pack contains 300 sheets (that's 10 packs of 30), so you've got plenty to last through multiple games and practices. The 17.3x13.4 inch size fits most athletic shoes perfectly, and the high-adhesion polyethylene grabs onto dust, dirt, and moisture from your soles instantly. Just peel off the bottom protective film, stick the mat to the floor, remove the top film, and step on it a few times - your shoes will have that fresh-out-of-the-box grip again! The numbered labels make it easy to track usage, and they leave no sticky residue when you remove them. Beyond basketball courts, these work great in workshops, labs, hospitals, garages, or any place where clean, grippy footwear matters. They're transparent so they don't look obtrusive, and the quality material holds up to multiple uses if you're careful. Seriously, if you've ever slipped at a crucial moment because your shoes lost their grip, these mats are worth their weight in gold. They're that simple solution that can actually prevent injuries and improve performance by ensuring your footwear has maximum traction when you need it most. Every serious athlete should have these in their gear bag!
