Circumcision staplers don't fall

[HerrBomb]

Hi all, I got stapler circumcision 13 days ago. It seems the recovery is going well, but I'm worried because staplers are not falling and are being covered by new skin stead. Only two of the staples are visible now and the rest are like inside the skin. I have read a lot of a silicon ring, but I never had any silicon ring. I'm not sure if the technique used in my case is something different... Do you think it is normal that staplers don't fall and stay inside the skin?
