I got a wallet when I signed up - find it surprisingly slim and it's padded too. You can sign up for one for free here: https://freestylediabetes.co.uk/freestyle-libre/free-wallet
Not sure how long it might take to arrive in the current climate obviously.
I keep strips, some lancets and my old lancing device inside it. Still use my one touch delica lancing device as I like it and it's smaller so will fit in the wallet. All much more compact than my previous meters ever were! Just activate sensors using the reader, then use my phone, so haven't looked for screen protectors.
