this pill box be extremely difficult to open once it be close . and I be not some arthritic senior citizen , but a active 35 year old with good dexterity . the lid fit too tightly once it be snapped shut , and the lip of the lid be flush with the bottom piece . very aerodynamic I be sure , but you 'll break all you fingernail try to pry it open . I have to use a nail file tip to open it again . also , the craftmanship of the piece be poor in general , especially for a item of this price . the sticker inside say `` make in Thailand '' , and frankly it show . save you money and look for something else .
