Lezyne Tool Insert Kit

 Secures into handlebar opening.
• Lightweight durable machined aluminium.
• Doubles as bar end plug.
• 3 O-ring sizes secures into most handlebar sizes.

Tool Insert Kit
Innovative hidden multi tool that discretely and securely inserts into the opening of a handlebar. It’s constructed from lightweight, durable machined aluminium and features hardened steel tool bits. The kit is easily accessible for quick repairs and is available in three versions with up to eleven different tool bits that suit today’s modern bikes. The end of the tool doubles as a bar end plug and comes with three O-rings that sizes the tool to fit securely inside most handlebar ends. Note: will not work with closed end flat bar grips.
 

Fitting
I think its good to give more info about the sizes if internal bar diameter these tools are compatible with (not that O-ring should be spelt with a capitol O)
