This is a Nanoblock of the Shibaura Institute of Technology Centennial Main Building. 400 pieces Comes with a drawstring bag (with the SIT logo) I purchased this and stored it at home without using it. The blocks are unopened (please check the photos). Recommended for university merchandise collectors and architecture enthusiasts. There are no noticeable scratches or stains, but there are some minor scuffs on the outer box. Please refrain from purchasing if you are concerned about this. Instant purchase is OK.
