These gloves radiate a slight enchantment and alteration dweomer if magic is detected for. 

Once snugly worn, they seem to meld with the hands, becoming almost invisible (undetectable unless within 5 feet of the wearer). 

Either or both hands so clad, if not already holding something, can be used to actually pick many sorts of missiles out of the air, thus preventing possible harm, and possibly enabling the wearer to actually return the missile to its sender as an attack. 

All forms of small, hand-hurled or weapon-propelled missiles (arrows, bolts, darts, bullets, javelins, axes, hammers, spears, and the like) can be caught. 

If the weapon magically returns to the attacker, then catching it simply prevents damage, and returning the weapon does not result in an attack.
