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 kindergartens and elementary schools, 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 to easily 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. I also sell other handmade items, 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. I look 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 #EntranceCeremony #Mark #SportsDay #FieldTrip #WaterBottle #Fluffy Pattern/Design...Print (logo etc.) Type...Water bottle cover Atmosphere...Boys Target age...Nursery school/Kindergarten/Elementary school
