Thank you for viewing. I purchased these with the intention of challenging myself in the serious mountains, but I have never used them. There is some dulling of the metal due to storage. Made by AIRMONTE, the size is unknown, but I wear a 27.5 cm shoe size, so I believe I purchased a size that would fit that. Approximately 41 x 19 cm. I do not have any pets and I am a non-smoker. Thank you.
