The tip is secured with double-sided tape. The refill is not inverted. I believe the HGG grip is made by ENO. The tip is slightly dull. This is handmade, so please refrain from purchasing if you are concerned about minor imperfections. You can buy it immediately. I will not reserve or hold items. No price reduction.
