You're welcome to call me and I'll match up the case you need to the Persol sunglass you have. Gary 1-800-840-2492. A FREE Micro Fiber Cleaning Cloth Storage Bag ($9.95 value) included with each case. International shipping for cases is done by EMS so it is trackable and the cost is my actual cost of usd$38.00 per package. That is for 1 case or 4 cases that will fit in the same Flat Rate package. I don't make any $ on cases and it is more of a service I provide for my customers.
