Stazon pad I think dries really fast (or mine did anyway..) so it is best to be purchased together with the pad the refill also..
The pad I didn't buy from this shop and maybe it was stored long..
So glad you carry this. My last bottle was getting low, and the refill is so much less expensive than purchasing a new ink pad when the ink in the (original) pad runs out.
Tsuknek is a great product
