Thank you for viewing my products! ♣ 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 is 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: Ivory ☆ Length: Approximately 20cm ☆ Width (flat): Approximately 9.5cm ☆ I have a dog. I am a non-smoker. ✮ Please understand that this is a hobby of an amateur. #UVtreatment #UVcotton #armcover #armwarmer #black #lacemaking #100%cotton #cotton100% #handmade
