Girth is the number that matters, not length. Circumference is what you actually feel and what decides whether something is comfortable. A longer toy at modest girth is far easier than a shorter one that is thick. Check the width on the product page before the inches.
Buy smaller than you think the first time. Almost nobody regrets going a size down, and a toy that sits in a drawer unused was the expensive choice.
ULTRASKYN for the feel, silicone for the lifespan. Real-feel is softer and there is genuinely nothing else like it. Silicone lasts for years, cleans completely, and can be boiled. If more than one person is using it, choose silicone.
Water based lube only. Silicone lube degrades silicone toys permanently, and over time it does the same to a real-feel blend. Water based is the safe answer for everything in this collection.
Real-feel needs powder, silicone needs nothing. Rinse, dry fully, then dust an ULTRASKYN toy with a renewing powder. Skip it and the surface goes tacky and starts collecting lint. Silicone asks for none of this.
A suction cup usually means harness ready too. Most flared bases here also fit a strap-on. Measure the base against your harness O-ring rather than assuming, because the widest bases will not go through a small ring.
Porous plus shared equals condom. ULTRASKYN and FIRMSKYN cannot be sterilized. If a toy moves between people or between openings, use a condom and change it. This is not optional.
