I just got these stockings but the seller sent me a way smaller size (A-B) than I ordered, I e-mailed them telling them about the problem and will keep you dear buyer posted. I cannot tell you about anything about the quality or color because I have not opened the ones I received.

Ex Output:
Negative


Ex Input:
Great. Gives you a pause to remember the real meaning of Christmas. Nostalgic and well loved. Without the glitz and flash of so much that modern Christmas has become. Simple and straight forward, young to old can enjoy it.

Ex Output:
Positive

This is a good book, but it does have some issues.If you happen to be looking at the Hardcover Import from 1994, there is an introduction from Donald Keene. In this introduction he pretty much gives all of the story away, including the final sentence of the book, and all the main events from the book. Luckily I caught on to this quickly and skipped most of the introduction, and read it after the story. This has happened in other books Ive read and I am unable to find a reason why these kinds of introductions are put at the beginning of the book.On a final note, the book can get slow and your eyes may start wander when the main character goes off on his long talks about his feelings and philosophical things, but if you can get past this, points will pop up in the book that keep you interested until the end. I recommend reading the book, and I will buy more books from this author.
