I am clearing out my parents' house. These items are quite old (about 40 years old). I am not an expert, but I don't think they've been used. They don't appear to have any rust, but they are old, and I'm not familiar with cross-stitch, so I'm sorry, but I can't explain any more than that. They are marked No. 19-23, but there are only 4, and it seems they originally came in a set of 6. Please take a look at the photos and consider them. Thank you.
