Optional hip flask Tips

Not because of the purity of ordinary steel, may grow over time rust, use stainless steel beaker and quality assurance more; material thickness also determines the quality of good and bad, generally better than 1.0 cm in thickness. Some hip flask thinner materials, hand vigorously what there will be pressure deformation;
2. Process: stainless steel electrode for welding, welding is a solid, high cost of technology; with tin solder, steel and tin can not be a good fusion, beaker and onto the floor easier to weld crack. Another body of tin easily trace elements intake, physical harm, so soldering hip flask is not in line food hygiene standards.
