I've bought those picks as a gift and they are extremely good. They came in a really nice package, that looked really good. The quality of those is also really good. They are made from a really nice and comfortable material, which makes a really good grip. After playing for more than a half of the year they are still in a great condition, so I can admit that the durability is great. The size of a pick is pretty much standard, I really recommend to use those for acoustic guitar, as the thickness is ideal for it, in my opinion.
Really recommended buying those, as the price is really good.
