I am using a 3.5cm hair clip. I will attach the non-slip grip to the top only. ★Please let me know if you do not need a non-slip grip, or if you would like one attached to both the top and bottom. ★If you wish to purchase multiple items together, please comment before purchasing. I will offer a discount of 100 yen for each additional item after the first. (❁ᴗ͈ˬᴗ͈)” If there are no changes, immediate purchase is OK. In that case, I will send it with the non-slip grip attached to the top only. (* .ˬ.)) *Please refrain from purchasing if you are concerned about the glue marks left to prevent the ribbon on the button clip from unraveling. *Please only purchase if you understand that this is a handmade item made by an amateur. *It may come off if pulled strongly. *Shipping will be via standard mail, so there will be no tracking or compensation. *Shipping will be suspended on Saturdays, Sundays, and holidays.
