I had the original zenlet in 2014, simple, dependable, finally died after nine years. So, I get back online google Zenlet, find it’s being sold out of Japan. I got an updated wallet, (without extra card slide). Was nice, had upgraded internals from plastic to include some metal parts. Worked great for a month, before the spring loaded mechanism just started opening in my pocket, basically, it’s not staying closed without clamping it shut. Bloody worthless!!
