On the Vertical wallet - I see you changed the description from "not optimized" to "not ideal".
That's probably a good call from a marketing perspective ... the phrase "not optimized" just stuck in my head as a negative. "Not ideal" conveys the same message but is gentler :p.
Anyhow - for your consideration -
1) Vertical wallet - make it 6 slots instead of 4, and add more currency idealness :)
2) Cardholder wallet - 6 slots instead of 4 would be great.
