About killing needles. The most common needle is the one that has one cut in the middle like the silver green, and the little blue one. Then you have different ones like these other two blue one that has just one cat. They are for different uses. Battery one has to battery inside, double A and they last a lot. only has one button that you have to press is very, very likely in order to use it.

Because if you press it very hard the paper goes from you this a this tool is only for a low waste paper. And the perfect use for this tool is to make stuff like I'm showing a lot of roles like a design like this one. And with this tool is faster to do it. Well, this is all about needles. Thank you see you in next class.
