准备交DIY的EB1了。想请教DIY的大侠，具体是如何装订的。USCIS的tips说：
Use ACCO fasteners to hold together thick or bulky applications or petitions
. Two-hole punching the top of the material for easy placement in the file
is appreciated.
具体是什么ACCO fasteners呢？在Staples找不到看着合适的啊。
还有：The use of tabs assist in locating items listed as attachments. The
tabs should be placed on the bottom and not the side for ease in filing。
这种tab具体买哪样的好？
大侠们能给个具体的Staples或者Office Depot的link就更好了。问题可能有点太菜鸟，嘿嘿，不管怎样，先拜谢大家的提点和帮助 ：）
