Normally the regular size of the different material zipper here is #3,#4,#5,#8,#10
but there are some big sizes for resin zipper ,such as #15,#20,#30
how big will be for the #30 giant resin zipper ? below some sample pics will give you some ideas ......
it's not mainly use for pull or mixed function , but also for decorations ,cool enough ,isn't ?
