Review on 🎾 KEVENZ 12-Pack Standard Pressure Training Tennis Balls - Enhanced Elasticity, Extended Durability, Ideal for Beginner Tennis Training by Troy Tec

I needed something soft to cover protruding studs on the underside of the top storage compartment which I don't think are worth cutting off but could cause injury , if someone climbs on or under the shelf. The screws were the wrong thread, which I couldn't find acorn nuts for, so I figured styrofoam balls, tennis balls etc are advertised for 'learning'), but as the price was quite cheap they are bright yellow and the right ones for my application Size. I planned to drill or poke a small hole in each ball, inject some Great Stuff expansion foam, then clamp the ball over the protruding nut (into the hole I made), and when the injected foam has set , it should form around the threads of the bolts and hold the balls on the studs fairly well, but I could still remove the balls fairly easily later if needed. The highly visible yellow color warns people and the large, soft balls do not cause injury. I've seen reviews from other people that these balls weren't very durable when used as toys for their dogs and I can't comment on that. However, I did notice that these balls have a visible raised seam underneath the furry cover, likely due to the sloppy molding of the rubber ball underneath. So I agree with others that these are not the highest quality tennis balls. Still good enough for my odd application.
