desertcart.com: stedi Manual Pin Vises Hand Drill Bits, 1/8 Inches Tungsten Steel Micro Drill Bit Set : Tools & Home Improvement Review: Yes, the case opens. - The drill bits are sharp, work fine on styrene plastic. But as a grown adult with a decent education and many years of construction, DIY experience and comprehensive knowledge of most hand tools, I hate that I was totally clueless on how to open the bit container! I was about to hack into it with a hammer and chisel before figuring out it was a SIMPLE opposite pressure on the two pointed plastic sections on the side that easily open the case. They should include step by step instructions with additional photographs and an audio narrative for old farts like me that still fight with child-proof caps. Review: Worth the purchase - I have been buying all their products. I always worry about cheapness and bad quality, but honestly, even the plastic containe for the bits is really solid.
