Leash is either 2 cm wide (for 2 cm collars) or 2.5 cm for all other widths and always 1 m long.
Take in count that these ribbons are fixed size (2.2 cm wide) especially when choosing 4 cm or 5 cm wide collars. Ribbons can be sewn in two rows if collar is 5 cm wide (2 in) but please add a note if you want this to be done.
Exclusive Webbing Designs are only available at 2, 2.5, 4 and 5 cm widths (0.8, 1, 1.5 and 2 inches)
Regarding the "Collar adjustment (regulation)" option - usually collars are made without regulation part because the loop of the attached leash will slide (as half choke collar) so that your dog can´t get out of the collar. With slider on the leash, you will be able to regulate how much you want the loop to tighten.
All products in my shop are handmade to order. Since I am sole producer, processing time depends on how many current orders I have at the moment. Current processing time (turnaround) is around 4-6 weeks.
For dogs with Sensitive neck or thin coat I would recommend to choose padded (lined) collar.
