膠袋尺寸如有不同, 請自行量度準確尺寸去修改。
如衹有一個膠袋大了或細了一點,就用單數(singular):
If the size of the plastic bag is different, please measure its exact size and make adjustment yourself.
如所指不同尺寸的膠袋多過一個,則要用眾數(plural):
If the sizes of the plastic bags are different, please measure their exact sizes and make adjustments yourself.
