Carolina Designer Dragons Leather Reptile Collar; Limited Edition, 10mm Regaliz Leather with Studs and Swarovski Blue Rhinestones These limited edition Leather Reptile Collars by Carolina Designer Dragons feature imported 10mm Regaliz leather from Spain and Swarovski blue rhinestones from Austria. They come in three neck sizes; 5, 5-1/2 and 6. The studs are the good kind with the threaded screw attachment through the leather, not the nail head type which could risk scratching your reptile. These Leather Reptile Collars add a bit of something extra to your bearded dragons already unique personality. They also come in other designs; featuring Swarovski fire opal, red or deep pink rhinestones, as well as a studs only design. Please see our other listings here on Amazon. These collars are certainly a conversation starter with others in our reptile community; when you take your little friend out for a walk or to a reptile show. (dragons shown are not included)
