PE light case inner pad key case

We processed the PE Light B-4, which has a moderate hardness, into cushioning material for the key case. The internal pad of the case can be produced through punching, and we will mass-produce the cushioning material.

B-4 is a polyethylene foam that is 30 times expanded. It is a material that is commonly used due to its softness, lightness, and relatively low cost. We also offer suggestions for finger holes for easy handling.
