Blue Part On The Eraser
These erasers are sure good at bringing back childhood memories. Do you remember what people used to say about the blue part of the eraser? They said that it would erase ink, but this is not true. It is intended for strong and thick paper! Artists probably found it useful when they had to use special paper.

Square Patches On Backpacks
Many backpacks come with those square patches, but do they mean anything? They actually do. That feature is known as a lashing square or a pig snout! Many of us have issues fitting everything we need inside the bag. The cool thing about it is that you can hang extra gear with this awesome feature. Neat!
