Thank you for looking ♪ This is a folding mobile phone case made as a hobby by an amateur. Height 14cm Width 7.5cm Gusset 2cm Material: Synthetic leather Shoulder strap 110cm There are chalk pen marks on the back, but they will naturally disappear with use. (Please understand that there may be slight errors due to amateur measurements.) It is not perfect like a commercially produced product, but I enjoy making it. Thank you for your understanding of handmade items.
