Thank you for viewing my products (*^^*)☆☆ Size: Approximately 21cm (length) x 7cm (width) Shoulder strap opening: Approximately 5cm ☆ Regarding custom orders, please see my profile (*ᴗˬᴗ) I have listed the conditions for accepting orders, so please check them (*^^*) The back side uses Russell mesh, which is used on the back of backpacks. It's a three-layer mesh with excellent breathability and cushioning, and it has [antibacterial and deodorizing] functions, making it especially recommended for the hot season (*^^*) Furthermore, because it has quilt batting in between, it's fluffy. It prevents the water bottle strap from digging into the shoulder and reduces pain ☆ At kindergarten and elementary school, there are surprisingly many children who have the same water bottle, and I've heard stories of children accidentally taking home a friend's water bottle (^_^;) By attaching a cover, it can also serve as a marker so you can quickly identify your own water bottle (*^^*) Please use it for removable water bottle shoulder straps, paint bag shoulder straps, etc. When washing, we recommend hand washing or using a laundry net. We also have other handmade items for sale, so please take a look (*^^*) #azuHandmade #azuShoulderStrapCoverBoys ↑ By tapping here, you can see only the patterns for boys (*´ `*) Only the water bottle shoulder strap cover will be shipped. The small items used for photography are not included. I make each item with care, but there may be slight distortions, misalignments, or double stitching. If you are looking for the strength of a ready-made product, please refrain from purchasing. Please note that the actual color may differ slightly from the photos depending on how they are taken. We are looking forward to connecting with those who understand handmade products. If you have any questions, please feel free to comment. Because I have a young child, it may take some time to respond. #WaterBottleShoulderStrapCover #ShoulderCover #ShoulderStrapCover #BeltCover #Handmade #Entrance #EntranceToKindergarten #Marker #SportsDay #FieldTrip #WaterBottle #Fluffy Pattern/Design...Print (logo, etc.) Type...Water bottle cover Atmosphere...Boys Target age...Nursery school/Kindergarten/Elementary school students
