I purchase glue by sometimes comparing cheap ones. This time I purchased this for the first time. I am purchasing it with confidence because it is 3M's. It is unknown whether it is as expected because it has not been used yet
It is a commodity purchased in December 2016. A black thing came out from around three months ago and I used it without thinking that it would be an ink of the pen, but since the axis in the middle came out, it stretched out and confirmed the black one on the screw It was not securely attached. Apparently it looks like mold. It is the first time. Is the other person okay? Is it? I will not buy this item anymore because it will be a good thing to change to another company. I was in a bad mood so I hurried to order other items.
