A lot of the toys in here have a tunnel length of about 4-6 inches, 6 being on a very rare high end. This is all just too short. Let alone how damn tight these toys are. Tight enough to make me go numb.

I'm struggling to find things that are looser / longer. Could use recommendations. 6.5 inch + ideally

I can search for "long" on the store but that doesn't exactly work properly unless it's in the name of the toy. And there's no way to filter on tunnel length. Regardless, if toys are marketed specifically for that, it's usually their only gimmick and they're garbage otherwise.
