Not only do they have tons of styles, sizes, materials, and design features to choose from, you can always completely design a collar from scratch! I opted to go for a premade style that I was able to customize. I chose the "Layered Dance Party" martingale collar with a plastic buckle. I changed the base color to hot pink and added an extra D-ring so that I could put her tags on a separate loop from where I hook her leash to. Doesn't she look stunning?

Right on that page, you also have the option to add on a matching leash or matching wrist chain! Price-wise, they are a great deal for all the customization you are able to get. Each add-on (extra D-ring, aluminum buckle upgrade, width, etc.) is a nominal fee of $1-2 more dollars. Overall the collar cost me $34 before shipping & handling.
Since customer service is a huge deal to me, I give them major props for being one of the best customer service I've had in a while! I had actually chosen a pre-set size based on their size chart and it was unfortunately too small for how the martingale collars work. I received an email back the same day from Nicole and they were more than happy to make a custom size collar for the exact measurement of my dog's neck! I was able to get the right size collar within a week of the original shipment date.
I've now had the collar for two months and there is virtually no wear-and-tear on it. I've had to wash it a couple times but the collar is very sturdy and will most likely have a long lifetime with Starla. I have to say, I definitely will be coming back to them for more products in due time.
Lastly, they give great discounts! For the first person to comments I will give you a coupon code for 20% off your first order.
So let me know if you have any more questions about the product, martingale collars, or just to tell me how beautiful my dog is.
Ciao!
