Overview
Twink's glasswork shop doesn't actually have a name, as it's simply a mare working out of her basement. Nevertheless, Twinkle Shine is always glad to have clients visit her at the shop for orders. Her house is located on the outskirts of Ponyville, Equestria. For additional information, please see Twink's wiki page or send her a tweetbird via

History
Twink started supplying windows for Ponyville after she moved there from Canterlot. Prior to Twink's arrival, Ponyville primarily had to obtain replacement windows from vendors in Canterlot. As a result, Twink's services became quite popular in the town since it dramatically reduced the cost.
Location
The shop is located in Twink's basement and does not have an entrance of its own. She very rarely invites clients into the actual workshop, preferring to conduct business out of her kitchen and leave the workshop exclusively for the actual glass work. The actual house is a little off the path on the way to Sweet Apple Acres as you leave Ponyville.
Services
Twink is happy to make just about anything out of glass for her clients. Her most common orders are windows, which she often finds rather dull, and her specialty is lenses, but she's been known to make delicate scientific equipment on occasion, as well as artistic pieces and aquariums. If you need something made of glass, she'll be happy to accommodate to any specifications. She accepts orders via tweetbird, but generally prefers to see her clients face-to-face.
