I own several because they are extremely well made in ideal dimensions. I have inserted TeleThought
filters in some while leaving others unmodified for visibility in darker venues. I have only ever
used the zipper to modify the wallet to my liking but never during performance as the pocket leads
to the same area and is much easier to get in and out of. This wallet provides basic, SUC-like
features which has served professionals for decades and comes highly recommended.
