Thank you for viewing my items from among many others! ♣ This item is knitted with UV-treated yarn. I think it can be used all year round. In the coming season, I think it would be lovely to have this lace knitting peek out from your sleeves. Since it's 100% cotton, I think those with sensitive skin can use it with peace of mind. Also, please feel free to contact me if you need any length adjustments. ☆ Material: 100% Cotton ☆ Color: Black ☆ Length: Approximately 24.5cm ☆ Width (flat): 10cm ☆ I have a dog. Non-smoker. ✮ Please understand that this is a hobby item made by an amateur. #UVProtection #UVCotton #ArmCover #ArmWarmer #Black #LaceKnitting #100%Cotton #Cotton100% #Handmade
