1. 2kg/4.4lb natural dragon rocks, with two sizes available: small 5-10cm /2-4 inches height and significant 10-15cm / 4-6 inches height natural Ohko dragon stone. They are cut with a flat bottom so they can stand in the terrarium easily. There will be two sizes mixed, which is my recommendation. Welcome any questions.
2. a small bag of rock powder and instant aquascape glue is included to fix the rocks. If you have cats/kids or need to move your terrariums often, please do use them.
For your reference, a large and two pieces of small rocks are about 500-700g / 1.1-1.5lb.
Those rocks are great for small terrariums. You put three pcs together, and you will get a shape mountain group. You will get some fantasy micro landscape if you have the bottom up.

3. Suitable: moss, small bonsai, tiny cacti, and succulents (to create a desert landscape)

4. One of the most popular micro landscape rocks for aquariums and terrariums. In large tanks, they are cut to make a landscape. But in a small terrarium, those small pieces are what you are looking for.
With instant aquarium glue, they are glued together to form cliffs, mountains, cannons, and caves.
You will get the most sharp, mountain-like micro landscape with those rocks.

5. I uploaded some terrariums made of those natural Ohko dragon stones to show how to use them. One of the video links:
