DISCLAIMER! All products listed are generally in-stock at all times. Depending on the need at any given time, local architecture students and our ordering schedule, some may be shown as available but are not in-stock at our store. If you order any that are out of stock, we will email you what's missing and see if you want the order shipped as is or wait til it's back in-stock. You can always call us to verify it's available prior to ordering. Thanks.
