※【Please be sure to read the profile before purchasing. If you have any questions, please inquire.】 This is a set of two differently designed shields and a shield attachment. 【Not sold separately】 ※The helmet is for the image of the installation and is not included. - Shield shape: Bubble & Competition type - Shield attachment method: Snap-on type - Size: Free size Thank you for viewing. It came out during home organization. It has been used a few times, and there are no noticeable scratches or scuffs, but we will decline those who are looking for the quality of a new product. The snap buttons on the two types of shields have an adjuster function, so I think they can be attached to general jet helmets, but I have not confirmed the installation on all helmets, so please understand that there is a possibility that they cannot be installed. ※Despite the above explanation, we will not accept any claims such as "could not be installed" after purchase. The snap buttons for installation are very tight for safety reasons. Please attach all three firmly.
