Quick question regarding medals from event box

We are getting 5 medals per characters in this collab event, with 4 different characters.

Anyone still remember how many medals we get from normal event where we only have 2 character's medal from reward box? +10 medals per characters per box?

I'm contemplating whether to go all in in this event so i can get to 2k medals for Envy and Glutonny, or wait for other events that featuring them exclusively.
