Definitely one of the more interesting items on sale here. Couple of questions:

1. Any warranty or comment on the quality/durability of the picks? I might be interested in getting a complete learner's set but I understand the learner's hand will probably be rough on the tools. Don't want something that'll easily break.
2. Would they also come with a tool-specific compatible guide/lesson?

Why not quote in USD so you don't always have to adjust prices?
