These harmoniums have all the same characteristics as the suitcase, but they do not fold. Temple harmoniums are less compact but more reliable.
We advise buying such harmoniums in temples for everyone because there are few moving parts and it is difficult to break them. Such harmoniums are used in the 24-hour kirtan in Vrndavana and Mayapur. They can be equipped with adjusting levers. In general, a great option if you do not need to carry it all the time.
