This is the best sleeve design i have ever seen from tenga.
It is very sleek, discreet, futuristic in design when compared to both black and white flipholes i used to owned.
The sensation and feeling is much better in depth when compared to previous tenga fliphole sleeves. All the major bumps and ridges can be felt intensively as they are more pronounced to previous tenga fliphole sleeves. The sleeve material is still as firm as previous tenga fliphole sleeves thanks to their excellent quality control of silicone.
The plastic shell of the sleeve is weaker due to thinner lesser material being used when manufacturing this toy. The original black and white fliphole are made with much more durable plastic shell which lasts longer.
Quality is great for this product , includes 2 sample lubes at the base of product and i can see it lasting a very long time . However for something close to 10000 yen i felt tenga should of included a few more samples of lube like they did with there flip hole black silver or red range.
This is really one of the best masturbators i have used. The quality is even better than what i know from Tenga and it is super easy to clean. Have used it around 12 times now and still the material is as firm as on the first day, so durability should not be an issue here. A total recommendation from me.
