Designed specifically for incremental anal stretching, the 4-Step Anal Training System is a beginner and intermediate-friendly kit to help train the butt to accept larger toys. With the smallest toy clocking in at a diameter of 1.75" and the largest toy with a diameter of 3", this set doesn't just take you to an "average toy size". Instead, the 4 Step Anal Training Kit is designed for those who know they want to play with larger-than-average toys - or maybe want to truly step into the "Size Queen/King" range of large toys.

It's worth noting that the diameter of the smallest plug is 1.75". This is still a large toy - the same diameter of some slimmer biological penises. If you're unable to take at least two fingers down to the base, you may consider purchasing this kit alongside an even-smaller plug to stretch yourself to the point of being able to take the smallest plug of this kit.

With the size of these butt plugs, self-use is recommended. While the 4 Step Anal Training Kit can be used with a partner, make sure there's very open communication about the speed of penetration. The plugs go from a tapered tip to a formidable thickness within inches, and it's easy to stretch a partner too quickly when you're unable to feel what they're feeling.

As the toys are non-vibrating, fully waterproof, and low maintenance, the 4 Step Anal Training System also lends itself to those who need a high level of discretion - or are looking to play in crowded living spaces. The plugs are simple to clean, simple to care for, make no noise, and can be used in any environment.

The 4 Step Anal Training System is made of silky smooth, feels-like-satin, silicone. This silicone is a fantastically luxurious type of silicone that your fingers will easily glide over when you touch the plugs. This silicone has no odor and no taste.

With the type of silicone that this kit is made of, each one of the plugs will feel exactly like the thickness it claims to be. The silicone is not particularly squishy or plushy. It has virtually no "squish" to it, so when you read the measurements, expect the plug to feel exactly like the size it claims to be.

Rigidity-wise, like previously mentioned, the plugs do not have much plushness or flexibility to them. They feel like thick blocks of silicone - which they are. The bases of the plugs have some flexibility near the edges, but otherwise, the plug doesn't bend or fold under pressure at all.

The plugs have zero texture to them. In addition to the textureless design making them easier to insert, it also makes the plugs easier to clean.

Each one of the plugs of the 4 Step Anal Training System is a carbon copy of each other - only slightly larger or smaller. This makes it a genuine "graduated" design. Each plug will be exactly the same in terms of tapered tip and base - but you only have to contend with a change in thickness and length.

The 4 Step Anal Training System includes some basic, yet functional, design elements. Each plug has a wide base. This base is made of a flexible silicone material that's more rigid near the middle and more flexible towards the edges of the base. This helps the plug rest comfortably between the cheeks during use without poking into the skin. Each one of the plugs also includes a short, semi-thick retention area. This retention area helps the plug stay in the body while wearing the plug. Along with that, each one of the plugs features a tapered tip - which helps you be able to slowly stretch the body as you insert the toy. With the tapered tip, you can gradually work up to the widest part of the toy without a sudden change in thickness.

As mentioned in the "use" section, make sure you're aware that the smallest plug has a diameter of 1.75". This is about the size of a slim biological human penis. If you're trying to "work up" to anal sex, this kit is probably a bit too large of a starting point. If you're already having anal sex and want to go larger, this kit can fit those needs perfectly.

With the tapered tip of each silicone plug, penetration with your new butt plugs is a slow - but tolerable - experience. The thickness of these plugs changes dramatically with each millimeter, though, so insertion of these plugs - especially if you're using them as stretching plugs - can be a slow-going process. Make sure to listen to your body as you insert the toys. As the diameter of each of the plugs changes dramatically as you go, you'll likely pause at multiple points during the insertion process. Make sure you're using these silicone butt plugs in a position that's comfortable to hold for long periods of time.

With regular use of the 4 Step Anal Training System, you should find yourself gradually able to insert larger and larger toys. It may require a couple of weeks of regular use with each "size" - especially as some of the graduations between plugs is particularly large - but with dedication, you'll find yourself reaching the final plug.

With the noticeably gigantic thickness of the biggest plug in the kit (3 inches diameter!), you will likely find uses for the largest of the plugs on a regular basis - even after you've finished using the kit for the "training" purposes. The largest plug can function as a fun public play plug, or it can be used as a gradual "set it and forget it" plug to help stretch for taking a large butt plug later on.

As all of these plugs are made of waterproof silicone, cleaning couldn't be easier. Warm water and anti-bacterial soap will clean up all of the plugs with no issue. You don't have to worry about getting water on the toys, so you may choose to let them soak in an anti-bacterial soap bath to further clean the plugs as well. For a sterilized clean, consider boiling all of these plugs in a boiling water bath. They should all fit into pretty much any standard pan.

As the plugs are made of silicone, the only water-based lubricant should be used with them. Silicone-based lube should be thoroughly spot-tested on the base to ensure that it won't destroy the plug's material if you want to try your favorite silicone option.

For storage, you'll find that these plugs don't really tend to attract hair or lint. In fact, a quick bath before every use tends to make them fuzz-free. You'll still want to keep them in something - like a plastic bag or a satin drawstring bag. Where you keep them is up to you, but the original packaging won't cut it.

The 4 Step Anal Training Kit comes packaged in a see-through plastic bag. Inside of this plastic bag, each plug is individually wrapped in its own bag as well. All bags must be destroyed in order to take out the toys - and the bags are not suitable for long-term storage of the plugs either.

The 4 Step Anal Training System includes no further instructions or information.

I'm genuinely surprised that the 4 Step Anal Training System starts with such a large-width plug. The thickness of this plug is going to be more than most beginners are able to take - and it's about on par with the thickness required to enjoy anal sex with your partner.

So that being said, this kit is really best-designed for someone who wants to go "above and beyond" anal sex. If you've had anal sex and want to start working up to huge sex toys, this is one of the few kits out there that are designed for that.

If you're just picking it up for anal sex, make sure you're able to take 1.75" in diameter - because that's the size of the smallest plug.
