Thank you for viewing my items from among many others. This product uses resin, so there may be some unevenness or small air bubbles. Each item is made with care, but please refrain from purchasing if you are concerned. m(_ _)m The length is about 7cm and the width is about 1cm. This is a hair pin that captures a moment as the season transitions from summer to autumn. You can use it as a regular hair clip, but if you wish, I can also attach a chain to connect it to your house keys or small items that tend to get lost in your bag. I have various other items for sale, so please take a look if you'd like (,,> <,,) If you are considering purchasing multiple items, I would appreciate it if you could comment before purchasing. I will offer a discount to some extent m(*_ _)m
