This is a great system that really helps with preparation and body maintenance for anal play. Previously I didn't have any smaller toys to use to work up to my dildo, which is a bit too large to start with, and this set works perfectly to prepare that. Additionally, now that I'm comfortable using the size 4 set, shopping for new toys is much easier since I have an upper limit to go off of.
The material is really smooth, feels and looks great, and the plugs are comfortable to wear. Looking forward to trying the next size up and the longer wands!
