Just 4 pieces, but made to fit each other (and priced at a discount if you buy them together in this kit). And it will save you a little time to buy them via this kit page, too.
This kit includes a chipboard facade (laser cut to match the shape of the color theatre image on the French Fairies Shadowbox Facade Collage Sheet), that same collage sheet, a matching shadowbox and a riser to fit that deep shadowbox... pretty much all the basics used in Tristan's artwork below!
While I'm explaining all these components, everything in this add-on kit is also available to buy separately (until sold out). See the "We Also Recommend" section, below, for links/pics to all 4.
