Quarter Watt (1/4W) resistors are the most used type of resistors that are used in simple electronic projects and DIY hobbyist projects. 150 pcs. resistance box includes has 30 values resistances (5 resistances each) (30 x 5 = 150).  In this pack we have following valued resistors: 1, 2.2, 4.7, 10, 22, 33, 47, 68, 100, 150, 220, 330, 470, 560, 820, 1k, 2.2k, 3.3k, 4.7k, 5.6k, 10k, 20k, 33k, 47k, 68k, 100k, 220k, 330k, 470k, and 1M ohm
