Quality OK-ish, Arrived Quickly / 6% Arrived Broken

ORDER: x50 Acrylic post-style pins with rubberized pin cap (bought at discounted price). #1 PRO: Image quality definitely worth the discounted (coupon) price. PROs: Economical price, fairly quick receipt of order. #1 CON: 6% of pins received broken & unusable. CONs: 18% of pins received with post attached significantly below center - they invert quickly during wear, despite a tiny "anti-rotation" (?) prong. Very few arrived with posts centered on pin. Would not order again with same level of quality control. Would not order again at full price.
