This is for 2 pieces of BC107B silicon transistors. They are from Central Semiconductor and are in a TO-92 package. They have a gain range (Hfe) between 280-400.
These are great for High gain fuzz face type pedals, or to pair up with a Germanium transistor for a nice hybrid fuzz face pedal.
Each quantity is for 2 transistors. They are gain matched within 10% of each other, so you have the best sounding pedal on the block.
