Which type of glove is best used when the risk of an item slipping out of your hands is significant?

The correct answer is PVC dot-tipped glove.

This type of a glove has small plastic dots on it, which enables the wearer to hold objects in his or her hands freely, without fear of them slipping out. These PVC dots prevent the fragile item (such as glass) to slip out of the hand by sticking to it.
