them.
So what made a man take {#blank#}3{#/blank#} collecting boxes as a hobby? For Kosuke Saito,

When Saito was opening{#blank#}5{#/blank#}Amazon
box, he noticed(注意到) the serial number"XM06"
{#blank#}6{#/blank#} the box. He suddenly remembered seeing "MX08"
on another Amazon box. He thought there must be an XM07 as well. He wanted{#blank#}7{#/blank#} (know) what that box was like. But it was only
the{#blank#}8{#/blank#}(begin), because he soon
found that Amazon boxes come in all{#blank#}9{#/blank#}(shape) and sizes, and he took a great interest in all of them. So far,
