This slipcase (and its complimentary sketchbook) is sold separately from the Tripping Over You volumes. Volumes that are purchased alongside it will be shipped inside the slipcase for their protection, however!
Orders for the slipcase are being handled as backorders. If you missed picking up the slipcase during our Kickstarter for Volume 6, this is your last chance to grab a copy! Orders are planned to ship early December 2023.
