This long-stretch ballstretcher is designed to stretch you, with its strongest squeeze concentrated in the middle. An hourglass-shaped inner grip gives the opening a contoured profile. That combination creates a distinct shape and pressure pattern to consider when choosing a ballstretcher. The stretchy construction combines TPR and soft silicone, giving you a flexible blend in this contoured design. It is phthalate free and has no scent, details that may matter when comparing materials and scent preferences. The measurements offer concrete references for judging its proportions against the fit you prefer. Width: At 2 inches (5.08 cm), this measurement helps you assess the ballstretcher’s overall width. Outer circumference: The 6.75-inch (17 cm) circumference gives you another reference for comparing its proportions. Inner circumference: The 3-inch (7.62 cm) opening measurement helps you consider the contoured grip. Material and scent: The stretchy TPR and soft silicone blend is phthalate free and has no scent. Before buying, compare the stated dimensions with the proportions you prefer. The concentrated middle squeeze and shaped opening make the design’s profile especially important to your choice.
