collaborated with a suitcase brand to customize hardware pull rod bases for suitcases. Made of high-strength zinc alloy through precision die-casting and grinding processes, the base can bear 80kg, stably supporting a suitcase full of luggage. The telescopic slot is tightly engaged, allowing the pull rod to stretch smoothly without jamming. The anti-slip foot pad design prevents the suitcase from sliding when placed, suitable for pull rods of different lengths, easy to install and quickly replace damaged bases. The electrophoretic rust-proof surface resists bumps and wear during airport check-in, helping the partner reduce the damage rate of suitcases by 62% and increase user praise rate to 96%.
