I was thinking of picking up a XyloDuo or XyloT3. I've noticed that the XyloDuo works with the holster, but it is sold separately. I have not found how to buy the holster on Ivyskin's site or eBay. I've also emailed and tried to call with no response. Also, does anyone who has gotten a XyloT3 know if it works with their holster. They don't mention it working with the product. Thanks.
