One of my mantras as a crafter and a product reviewer is "There is no BAD products- only finding the right one for the job at hand." And by and large, that is true. The only time when you really need to know "which is better than that" is when you have multiple choices in the same product category. And the main products except for lithium battery glue pen also contains lithium battery hot cutting pen. Remember to get the suitable accessories including glue pen accessorie and hot cutting pen accessories for your pen. http://www.subbuteo.com.cn/main-products/lithium-battery-hot-cutting-pen/
