Overview
This time I got my hands on NPG's "New Proof of a Masterpiece No. 004 Riho Fujimori" number four in the "New Proof of a Masterpiece" line. The original "Proof of a Masterpiece" series was NPG's big flagship for large-format onaholes back in the day, and they brought it back with a fresh numbering system in 2023.
A triple-layer build. This one's made from three separate material layers. Multi-layer onaholes had their moment a while back, with brands throwing around flashy "X layers!" marketing. But real talk it's genuinely hard to feel what two or three layers actually add to the sensation. A lot of the time the difference is so subtle you'd barely notice, which is probably why most manufacturers quietly went back to simpler, cheaper two-layer builds. So credit where it's due: NPG, who've felt kind of stuck in a rut lately, actually went for a real three-layer material here. Respect.
Insertion Feel & Internal Sensation
Honestly, it's been forever since I've seen a handhole with two holes on the market. Spec sheet says model weighs around 800g, which had me a bit nervous the second hole might mess with the main one's comfort. But pulling it out of the box, it's actually about 833g and roughly 18cm long. That's chunky for a handhole, but on an onahole it just gives the thing presence you pick it up and immediately think "damn, this is big."
The three-layer material might honestly be one of the smarter moves NPG's made in a while. The softness takes me right back to that fluffy, gooey material NPG used to nail back in their prime. The outer layer has a slightly firmer, thin film-like finish not quite artificial skin, but it feels genuinely nice in the hand. Combine that with the soft, squishy inner layer and you get this mix of elasticity and give where your fingers just sink in it feels like a modern remix of old-school NPG material, and the balance between texture and bounce works really well. It's a touch oily, smell's pretty mild though, and overall the material combo just feels like a genuinely good toy.
Time to actually stick it in. The sensation is gentle, low-stim, and just pleasantly thick. For a while now I've genuinely been unsure what NPG was even going for with their onaholes, but here the three big pieces thickness, internal structure, material feel finally click together, and it's honestly kind of satisfying to feel that happen. Nothing stiff or plasticky getting in the way of the realism, nothing overdoing it either. The smooth, mostly low-key internal structure combined with the soft material wrapping thickly around you makes for a really convincing insertion feel one I'd happily point anyone toward if they like it thick, gentle, and low-stim.
The walls look smooth and flat from the outside, but there are these subtle folds and bumps in there that give the insertion a wavy, undulating feel a natural little accent running through the whole thing. Near the very back, the tip nudges gently into a soft "kuposh" against the uterine zone. It's a subtle touch, but a nice one for a mellow, low-stim toy, and it keeps things interesting the whole way through.
The anal side has the same smooth, flat feel going on, minus the bumpy texture and the uterine accent from the vaginal side it's basically just a smooth, straight tunnel. It's also thin enough that you can actually see the outline through the material, which makes it feel a bit flimsier next to the vaginal side. The entrance uses a slightly thicker three-layer material, so don't expect a strong "sphincter" grip, but there's a light, bouncy catch right at the opening that adds a nice touch of realism. Stimulation sits low overall, about a 1 out of 5, so it's not going to be everyone's thing but the relaxed, soft immersion in all that thickness is really this toy's whole vibe, and there's still enough going on internally to keep it interesting even at low intensity. Solid pick if you're into relaxed, thick, realistic, low-stim onaholes.
Design & Craftsmanship
This is where the premium price tag actually pays off. The outer shell's got a clean, low-key finish, and the inner detailing is honestly some of the most convincing sculpting I've seen at this price the faint pink tone and the realistic shaping really stand out. Packaging is discreet and holds up well enough that nothing soft gets dented or squished in transit.
Verdict
4 stars feels fair. With this fourth entry, it finally feels like NPG has made something that actually deserves the name "Proof of a New Masterpiece."
Best for fans of thick, gentle, low-stimulation onaholes who value a realistic, well-balanced feel over raw intensity.
