I was sent a sample of Thalia picks once when I bought a capo, and also bought a sampler pack. Their picks wear out very fast. Some of the thinner ones wore out in 10-15 minutes of moderately aggressive strumming on light strings. The thicker ones may last two hours.
For comparison sake, I have an ebony pick from another manufacturer that I've used for probably 6+ hours which shows signs of wear but is still going.
The laminate layers tend to crack and break off on the Thalia picks in my experience.
They do smell nice
