I think it worth the effort to find out your local products that can substitute leather CPR. I found made in German products are among the best. Such as cars,cookwares, and aquarium filters etc. The German made Eheim canister filter for my 75 gallon aquarium, is so reliable, so quiet, and so long lasting. I don't know how to keep fishes without it..
If you need a testing bag, there is vintage
coach tote on eBay that is low price and worldwide free shipping. It will be under US$ 30 shipped from Japan to me, probably will be similiar cost to you. If you are interested, I can PM you the link. Just make sure to have it authenciated before buying. That bag simply just not my style.
Maybe I shouldn't say it here, but the seller marked my purchases before as "Gift". So no import tax as well..
