For more than one year my son has pins in his pouch and he uses every day at school. The collegiate attitude of my son, he is left-handed, is very good. Through these pins and the grooves for your fingers get used to not only a false and tense attitude. Even in "normal" pins, which he also has to replace the pencil case, pen his attitude is quite normal. Especially for left-handers that's a great idea, we also have the right to pencils. The shelf life is enormous, despite frequent sharpening and almost daily use! We are now 14 months, but now I have to buy new ones. And the price is unbeatable at the moment. The teachers at the school advocating those pins, so also no malposition creeps. The colors are great! The durability is great, the handling is great, you can not go wrong, you do not become cramped ... Highly recommended. The price, if it is not an offer is a bit expensive. However, one regrets not. In the durability. Moreover, they look great and "cling" to the right in the hand. My son loves these pins. And he is not alone in the opinion. Highly Recommended !!!
