what it is used for: landscaping your terrarium with natural material. It can glue stones, driftwood. It can fix the rockes together or on vertical glass panel, etc.
If you do not want to use styrofoam or polystyrene for landscaping, this glue is your need.

How to use it: Please check my video. It appears in almost all terrarium making video (available on Facebook and youtube). The tip is fill the gaps. You need something to connect woods or stones, beside the wood chips / cotton in the package, cloth, tissue will be ok too
Advantage: it dries in seconds. Please wait 5-10 seconds to check whether it is glued sturdy.

Please note： I do not make it. This is from a brand of a Hong Kong company.
