CD wallet recommendation please

I have found that the sleeves of CD storage wallets are commonly too tight to fit the two back-to-back CDs that they are advertised to accept. Can anybody recommend a brand that avoids this, please?

I have been using CD-wallets for many years and not had any of the problems other members of this forum have reported. The type I like best have only one CD / DVD per “page” but are large enough to take 40 discs, in 20 sleeves. I have some wonderful ones from a company called “PC Pieces”, but cannot find any mention of this make now.

Looking forward to your suggestions.
