The Padded easy eyes leather blindfold from Sinvention is a one size fits most, black leather blindfold with thick adjustable eye patches and a buckle closure.
Here is a short snippet from Willow Wand’s review of the The padded easy eyes leather blindfold:
“The strap kept slipping down. Being a belt buckle mechanism for the strap, it doesn’t fit all head sizes. Apparently my head size is in between two of the holes, and because the leather has no stretch to it, I was not able to pit it on the lower setting, and the larger one was too big.”
