長及闊皆約 1.5 英呎，高約兩英呎，
差不多是一個小型床頭櫃左右。
但奇怪在個甲萬係有碌嘅。
以我之愚見，甲萬係防賊人偷野嘅，
其設計一係鑲係
牆鑲係地，一係就重到搬唔郁。
但點解呢個甲萬嘅設計會有
碌嘅呢 ?
方便搬走 ? 不會吧 ?
會唔會有其他功能呢 ?
請指教一下吧。

Dear Ming.Kwong, You are right about the material of the wheels, but I still have some question about that. As the save box is not light, actually quite heavy; the wheels are made of metal; If the owner is moving the save box by the wheels, 地板死硬。 So, the wheels are still 無鬼用。 What do you think?
