What do you get? A handmade leather pouch with a matching finger loop.
Can you request a custom design if you dont want any currently for sale? Hell yeah you can!
What does it cost you? $25 USD
Shipping? FREE, unless you want it faster than the USPS
Why no string? 2 reasons, because everybody has their own preferred cordage and length, and because the thickness they will add to the envelope will cause a big price increase in shipping.
Please take a look at what is currently for sale and let me know if you have any questions.
