As the Happy Tree is manufactured with 1cm thick and solid corrugated cardboard, it is durable enough. Because the humidity resistant corrugated cardboard is durable, it has been used to pack heavy and expensive products. When the corrugated layers are being stuck together with glue, environment-friendly corn starch is used instead of chemical glue, which is harmless to human body.

It has very strong structure because you can assemble Happy Tree by inserting 8 panels of branch into the groove of the center. Panels of branch interlock each other into 4 round shaped grooves and so it is not disassembled easily.

It can be used as event tree able to write messages of wish and celebration at cafe like interior item and Christmas tree.
