I am 5'1" tall woman and am looking for a 30 lb kettlebell but am concerned about the thickness of the handle? Is it too thick for small hands?

Does these come in pairs or single

what weight is good for a starter kettlebell for a 64 yr old woman??

Does the handle on the 15lb have enough room for two hands (standard women's hands)?
