The Tokyo Marui 0.12g 6mm BBs are actually about 5.95mm in diameter and made with the very same process as their bearing manufacturing. This makes the BBs slim, consistent and high quality enough to be used in tightbores as low as 6.01mm as suppose to other BBs which might vary enough in diameter as to cause inner barrel abrasion or jamming. Though, it was mainly made specifically for the Tokyo Marui Boy's AEGs series.

Pretty cheap , yet well polished and plentiful. for someone who usually shoots .177 a lot, this is perfect for training cheaply, specially when used with electric guns with rechargeable battery or external power mod
