Please be sure to look at all the pictures carefully before buying.
I try hard to take great pictures that accurately describe the items I am selling.
M
any (but not all)  of the items I sell are purchased at thrift stores, garage sales/estate sales, etc.  Unless otherwise stated, they are used/pre-owned. Feel free to ask me any questions.
I am a retired teacher working from home and enjoy rehoming vintage and pre-loved items. By the time I am done researching, cleaning, photographing and listing a vintage item I have often developed a bit of relationship with it and have a real appreciation for how things used to be before they were new and improved. Sometimes they needed improvement!
If there is an issue with your purchase, please contact me so I can make it right for you.
Customer satisfaction is very important to me, as evidenced by my positive feedbacks (which I would appreciate if you are satisfied with your purchase and my prompt service).
I try to make sure all orders are sent out the same day I receive payment for the item or the following business day.
I add to my store regularly, so I hope that you will consider following me and checking out all of the cool treasures I find during my shopping excursions. Thank you so much! :D
