Very useful for making Arduino Shield, combined with Prototype Board (). Anyway, would be more convenient if it’s packaged in set for Arduino Uno shield usage with ratio of 6 pin : 8 pin : 10 pin = 1 : 2 : 1, i.e. ( 10 pcs 6-pin 20 pcs 8-pin 10 pcs 10-pin ) per lot, and hopefully with lower price ��
