This a TM itsy bitsy insert made from ABS composite. This is a direct replacement for the insert currently in the TM Itsy bitsy putter. You can choose your design with or without the grooves. It’s your choice. I can colour the grooves with any of the material choices but please stay within the categories. The insert can also be made in ABS, in these colours: Gold, red, black, white,yellow. And PLA in Blue, pink, black, green. (Weights in ABS and PLA vary) Because of how they are manufactured, I can’t accept returns on them unless there is a defect.
