I Am Hard Like Rocks For My Types Of Envelopes
I am sedimentary
Metamorphic that’s me
Or I am igneous
When it comes to regular envelopes
The standard business size
Usually white or brown in colour
Plain or printed with a
Company logo or slogan
I am basalt or gravel
I am granite, quartz or marble
When it comes to window envelopes
With their transparent window
Where names and addresses or recipients can be seen
For large numbers of letters going
I am flint or tufa
I am tuff, chalk or lava
When it comes to self-seal envelopes
With sticky strips on the back and on the flap
They save time with large volumes of mail
So I am schist and sandstone
I am shale, slate and limestone
I am clay
Any day
So I will never give my envelopes away
