Thank you for viewing my work. m(__)m This is a lunch box band with Velcro on the sides. The third photo is a sample of the same design. For schools that specify aluminum lunch boxes, two-tiered lunch boxes, and wooden lunch boxes, rubber bands are essential. As children start their school life, they will begin to have lunch boxes. Do small children have the strength to handle rubber bands well with their small hands? Stretching the rubber band while holding the lunch box and the end of the rubber with one hand. It's quite difficult. It can be difficult to remove or fasten. In the worst case, they might flip the lunch box and not be able to eat. This product only requires you to place the lunch box on the rubber and fasten it. You don't have to hold the lunch box, so it's easy to use. It's also easy to use for the elderly. In the summer, it's also easy to wrap around to secure ice packs to lunch boxes or PET bottles. The 2.5 cm wide black rubber has illustrations of cats and zebras on the sides, and it can be fastened with Velcro. You can use it from about 25 cm when fastened snugly without stretching the rubber. It stretches about 10 cm, but small children may want to use it up to about 5 cm. The Velcro is about 3 cm. Please check around your lunch box and choose a size that tightens it slightly so the lid doesn't open. Since lunch boxes come in various sizes, please be sure to check before purchasing. If you comment before purchasing, I will consider custom orders. This is handmade. It's delicate work, so I try to be careful, but there may be some imperfections. Please understand and purchase if you can accept this. In addition to this, other sizes and other designs of rubber bands are on sale. Please take a look at my shop if you like. Thank you very much!(^^)d
