I got these ages ago and since I don't usually have a partner, I put them to use with some standard bullet vibes. They add a different experience (if slightly muted thanks to the silicone) and more texture than I'm used to. They did not have any taste or smell when I opened the package and the seam on it is barely felt.

The packaging is not discreet, but you could pass it off as a massage aid if people don't look too closely. Also, the 4 finger teasers come in a clear, plastic bag with no instructions inside (instructions are on the back/side of the box).

They seem to fit most slim fingers up to the 2nd knuckle(about 1.5 inches long) but wouldn't fit on a friend of mine (who is on the larger side), so I'd suggest that these be used for toys rather than hands. It's a bit difficult to feel the person through the silicone, so I advise against any penetration. Playing with the clit, head of the penis, and anus is fine (sanitize between areas and partners!).

They're really easy to clean (especially if you own a dishwasher). Just clean with soap and water, or place them in the top rack of your dishwasher when you've got time. Dry them off and store anywhere you want (just keep in mind that the silicone attracts dust and needs a quick wipe-off before the next use).

Only use water-based or oil lube with these (the finger teasers are great for massages!), using silicone lube may result in the toy warping.

One downside I've found is they get lost easily and if you have a cat/dog/other small animal, they may steal and destroy them, so keep them far out of their reach. I've lost 2 out of the 4 I had when my cat stole the pink and orange ones to play with.
