A rounded-off, slanted pair of tweezers, so to speak If you do not want to work with ends and corners that are too prominent and want to avoid any risk of injury, the Safety Tweezers are the right choice. We recommend that you always use the protective cap provided when storing your Rubis tweezers after use. Every pair of Rubis tweezers is handmade and although the tips are durable, their functionality may be compromised if the tweezers accidentally falls to the ground.
