Have not tried these as of yet but will pick up a 20mm in blue for a watch. I love these FKM straps as I think these are my favorite as far as straps go. Ordered a few from StrapsCo. Very comfortable, no lint and I love the look. Under $20 is a good deal.
side note: cancelled my StingRay strap from OC. After 1 month no email stating any tyme of shipment. Emailed Christian and he stated that his "strap maker" would be finishing up on this custom order even though the website showed that there were 2 available. Ordered from your suggestion from 7strap at less than half the price. OC gets these overseas and acts like they are making them themselves. I am done with OC and Christians
