Marna is a multi-functional opener. It's an opener that easily opens cans, bottle caps, and PET bottle caps. I received this as a gift and have kept it at home for about six months, but I'm selling it because I don't need it. [Easily Opens Lids] This multi-opener can handle various items, including bottles, PET bottles, and pull-tabs on cans. It requires little force, making it a recommended kitchen tool for children and the elderly who have less strength. Thank you for looking. #Marna #Opener #KitchenGoods #marna
