Safety locks with nice grip. Have been using them for 2 years now. The glue lasts longer. Good for all kinds of cabinetry, single and double door. Would have been great of extra tape is included in the box just in case someone wants to reallocate the area. Worth buying for infants-toddlers who loves to explore unseen areas. For removal- you can easily take them using a scale or knife. Leaves no stains or glue marks if used on laminate.
