Quality construction, should be very durable and should last for years. This case allowed me to get rid of my "box" of taps and associated bits, allowing me to quickly select the correct tap and identify the correct tap.
Pros
which have 36 taps and drill bits in thread sizes from #6-40 to 1/2"-20 (NF) and #6-32 to 1/2"-13 (NC) and pick up drills. Sizes #33 to 29/64" (NF) and #36 to 27/64" (NC)
