Thank you for your review and feedback. We appreciate it! There are slight variances in all production runs of BioThane. If your leash is slippery, particularly in wet conditions, try washing your leash or long line in mild dishwashing liquid mixed with warm water. We suggest using the grease-fighting kind to remove residual oils from the manufacturing process, as well as sunscreen and/or lotion. You will want to rinse your leash really well afterwards and wipe it dry. Kind regards to you and yours!
