| 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). |

Quality valet tray, darker brown
Color: Brown, Color: Brown
Sizing is as described and it is sturdy and well-made, but color is not quite as shown in the product images, more of a darker brown.

Absolute Gamechanger
Color: *Black
I went from casually dropping everything onto my nightstand in it’s designated spot to actually being able to store things neatly. The organization is insanely satisfying on top of just looking better than a bunch of loose items on a table. The size is quite large but you should know what you are getting. This tray offers a ton of storage for both small and large pocketable items. I even have a bit of extra room for my glasses or future EDC. Build quality is insanely solid and I have no qualms with how it functions. Worth the money.

Almost Great
Color: *Black
This is a better-quality night-table/desktop organizer with enough space to put most of your EDC or pocket items, including cell phones, chargers and even some jewelry. Definitely better than most others and worth the price. The only reason it didn't get a fifth star was the placement/ergonomics of the charges/wires. there are two (2) holes for wires for phones. There are more than enough spaces for phones, and other devices. The holes are just too small for more than 1 or 2 wires. not enough room. There is a great cut out on the size for pens, and another area for jewelry or cuff links. well thought out - but again, a tad small for today's user. Overall, well made, looks nice, can fit almost everything
