Hey archery enthusiasts, if you're tired of inconsistent shots and want to get your bow perfectly tuned, this SOPOGER archery kit is exactly what you need. The T-square ruler measures 13 x 3.8 x 0.39 inches and attaches right above and below your nocking point to help you get those measurements spot on every time. The nocking pliers are seriously handy - they've got comfortable grip-coated handles and measure 4.3 x 2.2 x 0.6 inches, making them perfect for slipping into your quiver pouch or bow case.
