I tested the three models and noticed that the 28 and 38 year old ones felt similar in texture.
Also, the artwork on my 38 model is slightly blurry. I don't know if this is a common defect.

Overall, though, it was a good experience. The size of the cup is ideal for travelling or for keeping in your backpack — if you can hide the illustration, that is!
As with the Tenga Air-Techs, if you know them, the cup and suction hole at the top produce quite the noise when thrusting, but using the sleeve without the cup solves this issue.

For medium length and girth, I'd say the wrapping is adequate.

In terms of cleaning, removing the sleeve can be a bit tricky at first, but you quickly get the hang of it.

I'd recommend giving it a try if you're looking for a pocket-size onahole with a nice packaging (though I'd recommend more the Nezuko Blowjob if you can afford it).

Warning: No lube included!

()In the attached picture, I put the Ona-Eki lube next to the cups for scale).

The product itself is very well made and I like the artwork and how it is self contained and easy to clean but If your like me and prefer a harder more stimulating experience,I would avoid this one but if you prefer a softer feel and ease of use its a decent first buy given the price.

I'll start by saying that when I first tried the 18 years old cup, I was a tad bit disappointed. It’s super tight (a little too much) and honestly, the texture felt almost non-existent? It still got me off, but it was too snug and kind of meh in terms of how it felt. Not sure if the texture is a little too soft, or if the tightness made me numb to it ...

Then I moved on to the 28 years old cup, and oooof, that one is wild in comparison. It's definitely still on the tighter side, but the texture and the variety? Damn, gave me one of the best orgasms I’ve had with a sex toy! If it were just a tiny, tiny bit wider, they'd be essentially perfect imo.

I haven’t tried the 38 years old cup yet, but judging by the more complex texture, I'm sure it'll be interesting!!! A few things to note tho:

- These cups are fortunately quick and easy to clean, mostly because of their small size. The 28 years old one did need a little bit more attention with all the varied textures and the tightness (guessing the 38 will also need a little more work), but still pretty easy (the drying sticks Motsu sells are perfect for these).

- The suction is crazy strong with them being closed, which is cool, but it makes them pretty noisy. The air coming out of that tiny hole in the cup gets loud, so make sure you're either alone, with your partner only or have some music blasting while going at it lmfao

- When I tried to disinfect the cases themselves with sex toy cleaner, a little bit of the paint started coming off. Might be my method or the cleaner I used itself (Fleshwash, the one sold by Fleshlight), but just a heads up.

- If you’re on the thicker side, these might definitely be overbearingly tight. Totally agree with the other the review on that one, but I do like them on the tighter side personally and I'm only average girth-wise.

So overall, it seems like a fun bundle so far, with different vibes in each cup! Totally worth it.

I'll start by saying that I'm very average in length (if not below avg), but girth wise, its a thicc boi.
I have used cups before (mainly Tenga) and I had no issues with them, but with these ones, I just couldn't fit...

The bad:
- The opening is too small, I could only fit the tip, not the shaft.
- And if I tried to force it would hurt because of the plastic rim.
- It also had a bit of an industrial, plastic/rubber smell.

The good:
- The material is soft and seems good quality
- The ribbing inside feels really good when I put my finger in it (which got me really excited at first)

Verdict:
If your boi is long and thin, I'm sure you'll enjoy these. But if it's thicc, then I do not recommend these cups.
