I already have a set of these bits - - and love them. My set came in a nice plastic case. Each row of bits slides out separately and the bit size is clearly marked on the front and back of each row. Very convenient and convenient. So I ordered another set (Dewalt #1369) for my son as a gift. The advert for the drill set showed the exact same plastic case I already had and the specs said the material of the case was plastic. However, what I received was a huge disappointment. The case was cheap thin metal. Rows of bits are locked - they don't oscillate. The bits were difficult to replace once removed from the case. The thin metal had already been bent and damaged in transit and all the small parts had fallen to the bottom of the case and were extremely difficult to reach. Luckily there is a 30 day guarantee so I sent the kit back the next day. Ordered a free replacement. Hopefully the interchangeable body will be a plastic version with each row fold out.
