protective case for iphone SE 3 gen (Huron and Wellington)

i'm lucky to have been given a used iphone SE 3rd generation. currently it has a magnetic case which sticks to keys, coins, fobs and more. almost lost my keys! not good.

yes, i could easily buy a new protective case for it, but am hoping you might have one on an old phone you are not using now, or have switched out? why bring a new case into the world when there are already so many??

if i could choose a new-to-me case ... i'm 'practical' and would look for a plain colour, clear, or muted pattern. not fancy, preference is not for sparkles or shiny!! :) NOT something magnetic, or with a cover that folds over, thank you.

i am conscious of green miles. i live in the wellington west area and would want to walk or bike to pick up. i could also coordinate with other tasks and bus or drive to minimize use of a vehicle.

hope i don't sound picky? thank you for reading and considering!
