Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed thickness is 0.040". 2 Slotted Valley Bolts. Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.Shipping Notes

Great birthday present for guys
Color: Coffee & Orange
I purchased this for my son’s birthday, he loves it. He’s into his watches and jewelry so he needed something appropriate for his growing collection. I think it’s a great value and it looks cool, the outer material looks a bit like carbon fiber, the orange is a darker burnt orange than pictured, but it looks nice. Fits all the stuff well, works great.

classy, sturdy, and keeps my watches looking sharp.
Color: Black & Apricot
This watch box is perfect for organizing and showing off my collection. The build feels solid, the top adds a nice touch, and the compartments are spacious enough for both men's and women's watches.
It looks great on a dresser or shelf, and everything stays dust-free and easy to grab. Whether you’ve got a few favorites or a growing lineup, this is a stylish and practical way to keep them safe and organized.
