Fi Compatible 3/3+ 1" Width BioThane® Martingale Collar

Amazing

She was super patient and helpful in helping me get the perfect fit and style for my fur baby. We love it. ❤️ thank you!

Love it!

They had our color yellow and were super easy to work with. We need a FI3 collar with a martingale option and we were even able to add a name plate. It looks super sharp on my black Rottie! Yellow really is our color. Thank you!

We love Sunflower Company

We recently purchased the Fi compatible Biothane martingale collar, which April customized even further and added a buckle. We love the fact that it’s waterproof and smell proof, and the colors are beautiful. We have several items now, and everyone of them is beautiful, sturdy and durable. And the fact that you can easily have them customized is amazing. So glad we found this company.
