On the search for a cheaper alternative to Zweckform and Co, I came across these labels. I thought at the price is not much lost and did a test purchase. Lo and behold, the labels are absolutely great! I see no difference to the known, 2 to 3 times as expensive label brands. I use these labels for franking my shipments by German Post and had no problems. An absolute Kauftipp- for me (and especially my wallet) there are now only those labels!
