If you are allergic to perfumes, smokers,  dust dander, pets or afraid to get your hands a bit dirty, things of that nature then I am informing you now that these items may contain 1 or more of these. as I get all my items from different places and many items may contain these and I never ever clean jewelry as I have way too much and mainly because I do not want to harm the piece. Email me first and ask because most times I can remember where I got the item(s) from and will inform you honestly.  I have pets also and once in awhile my kitty likes to help me when I am working :) Many of my vintage jewelry and findings come from a old warehouse and the baggies these are kept in smell of dust, smoke or both as they do permit smokers there. The jewelry items inside the bags should not smell, just replace the bag is all that is needed but if you are allergic, I am letting you know ahead of time as I do not want to be the cause of your allergies kicking in as both my daughters have allergies and know it can be a big pain. Thank you for understanding and may God Bless.
