This case was designed to provide years of use without needing constant repairs. The interior lining is 1/16" thick ABS plastic.
It replaces the traditional chipboard lining used by casemakers for years. Chipboard is made of paper and will eventually delaminate, leaving the case integrity compromised.
Stitching is also an important feature of your case. If the stitches are made with a machine not designed for the job, you will soon realize that the thread was not pulled tightly enough and loose stitches will quickly break.
We use a "Union Lockstitch" machine that pulls the tightest stitches in the world. It was designed and built in the USA and still provides the finest stitches today.
