Please visit (and follow) my store. I have many other items in many categories.
I do my best to accurately describe my items but if a problem arises just contact me & we will get it resolved. I ship every weekday & leave feedback quickly. I do combine shipping. If you are bidding on multiple auctions or are buying more than one item at a time let me know or wait for a combined shipping invoice. If you have any questions, feel free to ask. If you receive the item and there are issues, please message me so that I can try to resolve the problem. I try to describe the items as completely as possible but, sometimes, things are missed.
