I picked this set of Vivitar Close-up filters in 35mm size up at the local camera shops' annual tent sale. The optics are quite clear, with no major or noticeable marks that would affect image quality. I do not have a case for them, but they will be carefully packed to prevent damage and ensure safe delivery. I'm asking essentially $12 for the set and $3 to cover shipping. If you have any questions please ask! Shipping will be via USPS first class mail insured against damage. I have plenty of feedback here as well as ebay and pentaxforums under the same username, with 100% positive feedback. Thanks for looking!
