Went into LV to look.....
I'm sorry! I didn't get the #.... I'm sure you could call any store & ask... Sorry!
It is called Bolt Keychain.... They still have them in gold or silver... & they are $130. I love the chain with the Eva, but they said LV does not make a chain that could be put on the pochette

I'm giving in & buying the gold one once it's in stock next week.
