The size is decent, but using lube is enjoyable :)
The inner dildo is on the smaller side, and with the outside sheath it becomes more filling. The outside skin is very firm and does not more easily, not even when using plenty of lube.
I'm used to playing with much bigger toys but this is fun nonetheless.
Highly recommend for beginners, the ability to take off the sleeve (foreskin) is good for adjusting the girth you want to play with.
