This bundle is better than I expected: it includes stand-up doors, both wooden, and iron. There are many different shaped, sized rooms, caverns, traps, etc. I doubt I will need any sets beyond this bundle package, as it contains virtually everything I will need: two Dungeon Sets, two Caverns Sets, and some traps (fire jets from walls; lightning bolts from walls; slime pools/gushing from wall; water pools/gushing from walls; pit traps of many types; mechanical blades coming from passage walls; and more.
To ensure the longevity of my printouts, I printed on 110# cardstock, but then I covered them in clear contact paper, which will allow use of water-erase pens. To take them a step further in endurance, I purchased the least expensive, peel-n-stick, vinyl floor tiles (12"-square) from a local DIY store, $0.45/square foot. After clear-coating/laminating the top with contact paper, I apply them to a tile's glue side. To cut them, I use utility scissors, as an X-acto Knife, and steel ruler, are too tedious, and hard on the hands. The tiles give them some much needed weight, and they will be that much more durable, in the long run.
To use them on the tabletop, I put down some black felt, for a base surface, then I place the tiles on top of that, pieced together, to form the dungeon. The combo set has a very great deal within it. It is something I would very highly recommend to anyone. I chose this over 3-D stuff, because it is much easier to transport, and store; it is much faster to deploy into a dungeon on the tabletop, and my figures won't hit the walls when I place them on the dungeon map. Fantastic product, top quality, easy to use, and very affordable. Cheers!
