What is the etymology and usage of 爱不释手 爱不释手

be so fond of something that one will not let it out of one's hand



So I'm guessing 爱 would be the being fond of something and the 不释手 would be the not letting go. I feel like it's missing structure like it should be something like 他爱他的{Object}不释手

Is there anything more to this saying and how would it be used in practical speech?
爱不释手 is idiom in Chinese. You cannot split and use it. In most time, we use it as adjective or adverb to describe that you love something very much. 

Common Usage:


爱不释手的{Object}
他对他的{Object}爱不释手
{Object}让我爱不释手


Sorry ,I miss the etymology:

南朝·梁·萧统《陶渊明集序》：“余爱嗜其文，不能释手。”
