Thank you for viewing! I've crocheted a cover for plastic bottles and water bottles. It's the perfect size for 500ml and 600ml bottles. As shown in photo 5, you can attach a commercially available shoulder strap (not included with the product). Size: Diameter: Approximately 8cm Height: Approximately 18cm (Please note that these are hand-measured, so there may be slight variations.) ・Each item is carefully made, but it is a handmade product by an amateur. ・There may be some distortion or fraying. ・The color may differ slightly from the actual product due to the photography. ・The plastic bottle in the product photo is for size reference only. (Please note that it is not included.) ・Although unused, this is a handmade item, so it is listed as having no noticeable scratches or stains. Please understand and agree to the above before purchasing.
