| Remark | When using the Big Operating Cylinder, the stroke amount of the cylinder decreases, so please adjust the stroke as necessary. 1) Be sure to clamp the hose with a hose clamp to prevent air from entering before removing the standard operating cylinder. 2) Fill the Big Operating Cylinder to be replaced with Brake fluid, remove air beforehand and connect it to the Hose. 3) Even if you do 1), 2) work, air enters the piping. Once the air enters the piping, the pedal stroke and feel change. Because it is difficult to remove air from the thick diameter U-shaped pipe etc, please bleed sufficiently. 4) To facilitate the work of 3), air bleeding by vacuuming is effective (Please use the U-shaped pipe dismantling adapter attached to the NISMO clutch hose). |

Simple, Functional, and Adorable Jewelry Box
Color: Cream, Size: 2-Layer, Color: Cream, Size: 2-Layer
Cute and practical organizer with good space for everyday jewelry. Quality is good for everyday use, though the closure isn’t very tight, so it’s best for smaller collections. Great option if you don’t have a large jewelry collection. Overall, it’s a solid choice for keeping things organized.

Really nice box
Color: Cream, Size: 2-Layer
This actually is a very nice box. It is sturdy enough for constant handling. It does not hold a lot of pieces but I knew that. This is for someone that needs to store a small amount of jewelry. I like the sides that open and the bottom storage, it is big enough to hold small boxed with earrings in it.
The cover is very pretty with the padded look, it opens and closes very easy. One thing to keep in mind that the pull out erring holder is just covered cardboard, don't bend it. All in all I am very happy with this box so far it is doing what I need it to do, hold my spare jewelry.

Perfect organizer
Color: Cream, Size: 2-Layer, Color: Cream, Size: 2-Layer
This organizer is cute and compact but has a place for every type of jewelry which is what I was looking for. Its not bulky and i love how the two inner sections pull away to reveal a pretty large storage section for larger or micellaneous items. Would recommend.

Large and Conveniently Versatile
Color: Black, Size: Extra Large
This isn't quite what I was expecting but it is amazing. It is larger, sturdier, and heavier than what I expected. I emptied 4 other large decorative boxes of jewelry and relocated them into this. I cannot believe what it holds. The variety of drawer designes are perfect. There are ideal spaces for my chunky necklaces and bracelets. The side hooks are perfect for a multitude of light necklaces and chains. Love the top tray for a gazillion stud earrings. For the first time I have one location for my jewelry where I can actually see what is there without digging. It is a little too big for my dresser but the convenience is worth it. I got the black because it was the least expensive. It is a classy look. The color and design would suit a guy with lots of watches and bling or a gal with a variety of styles of jewely from chunky to light filigree. It is heavy even before loading it with jewelry. The drawers can easily be reconfigured with convenient criss cross dividers. All are nicely, lightly lined. It arrived well packaged with corner protectors. There was a bit of a smell but it was gone after airing it overnight in the bathroom.
