I started making these because my child's shoulders would turn red when carrying their randoseru backpack, and as a parent, I wanted to do something to alleviate the pain. I started selling these hoping that children with similar concerns could use them (*^^*) After much trial and error with shoulder covers that would slip, I devised and have been producing snap-on randoseru shoulder covers for 8 years, with over 6,000 transactions! This time, we have renewed the size and reduced the material costs, allowing us to offer them at a lower price (*^^*) Most children use these not only in the summer but throughout the year (*^^*) ✔️ Handmade by an amateur The seams and finish are not as perfect as mass-produced items. Snaps are attached with a hand press!! They may come off if pulled strongly. Please hold the snap when attaching and removing to make them last longer ♡ If a snap comes off, we will provide a warranty only within 2 weeks of arrival, while the transaction messages are available (*^^*) After that, please handle it with commercially available snaps (_ _)人
