First of all, the item's title is misleading. This is NOT a 'Service for 13'. It does contain 65 pieces, but it is a service for 12, plus five servicing pieces.
While the table/soup spoons and dinner forks are regularly sized; the teaspoons, salad forks and knives are oddly oversized.
For the price (and considering this is an online purchase I was unable to see with my own eyes before ordering), this is an ok purchase. If I were to see the odd sizing at a store, I would not have purchased the set.
