They told me it’d glow brighter if I hit it with a UV light, so I tried it… and wow, it really does. Kinda magical, haha.
Didn’t realize the letters would actually glow in low light lol. I was just checking the collar in a darker corner of my room and boom, glowing. Kinda obsessed. Super cool and makes the collar look way more special.
We absolutely love this glow-letter custom collar and leash set from Cosmos—so we’ve purchased it multiple times!
This set has been perfect for my pug, Lisa. We first ordered an small collar when she was around 6 pounds, customized with her name in reflective glow letters. Pugs can be prone to breathing issues, so I’m picky about gear. This collar is soft and lightweight—easy for her to move. As she grew, we upgraded to a size M collar; it now fits perfectly with plenty of room to adjust. Since Lila isn’t a heavy puller, this combo gives her comfort and secure control.
Another big plus is how easy it is to clean! The finish wipes down quickly after park dust, and the glow letters stay sharp and visible for dusk walks. Overall, this is a fantastic collar-and-leash set for dogs that walk well on a leash. If you’re looking for something stylish, adjustable, and comfortable—with nighttime visibility and personalized dog name —I highly recommend it!
I will never get another collar other than this one. The letters are all so cute and look so nice on my dog and the material is so easy to clean! I get compliments from everyone that sees her! especially during the night walk!!!
Bought this as part of my little girl’s birthday outfit. The collar and name letters are gorgeous and perfect for a night walk! I can’t recommend this set enough.
Buckle has a satisfying snap and hasn’t loosened once. Ordered a second color for spring.
Loving this lightweight leash with the matching collar.
