Anallock - Steel cockring with anal lock - 45 mm (M)

I previously bought an Anal Lock 40 mm Cockring from KissKiss and, as with my other toys, got very fast and discrete delivery. Thanks. With the 40 mm, I initially had difficulty getting it on. A bit tight for the Cockring and too large with the ball. After some patience I managed to get it on and as noted in my other review, I really enjoy it. After some time I decided to upsize to the 45 mm version. Again, great delivery. Also again it was difficult to insert the ball initially and of course, the cock ring was easier. I did not immediately notice any different internal feeling. Then I went for a walk. The feeling of the extra size and weight was amazing. Later on I switched the 45 mm ball with the 40 mm cock ring and at least for a couple of hours, this combination is even better for me. Here is my request: I can imagine that after some time I might want to further upsize to the 50 mm ball, but don't want nor need a 50 mm cock ring. It would be great if KissKiss sold individual replacement balls (of course also at a reduced price).
