We have a large inventory of parts. Some are used and some are new. We always try to find and list unique parts. My husband is also a Modular Building MOC builder and his unique creations will be on here as well. While we may be a newer store we guarantee customer appreciation. We will NEVER list parts that we wouldn't be willing to use and we have pretty high standards. 😉 If you ever have questions please feel free to ask and I will try to answer asap. Thanks for looking and have a great day whether your sorting or stacking!
