This unique and exquisitely beautiful glass Caterpillar Shaft is designed for vaginal or anal penetration and thrusting, as it has the required flared base. Feels sensational while rubbed up and down your clitoris as well. Inside the base there is a cone shaped indentation that will hold the whole of your distal phalanges {or the top bendable part of your fingers}. However the best use of this Shaft is for finding and then massaging the G and P Spots. The angle on Caterpillar head and the hump (which does most of the massaging) is what makes it ideal for both G-Spotting or P-Spotting. And a most thorough massage of each. The large mushroom shaped, flat topped head is perfect for clitoral stimulation as well. A truly versatile and functional piece of glass artwork I'd say.








The texture of this glass wonder is hard, slick and smooth. The mushroom shaped head itself has a rather rounded bulging ridge to the bottom it, as well as a penis hole on its flat top. The caterpillar hump in the shaft is most notable, hence the Caterpillar name. This hump in the shaft extends about 2" outward, past the head and base, which are lined up straight on top of one another, separated by this hump. I found the best way to insert the Caterpillar is with the head tilting up, the hump in its upward position. The glass toy is quite solid and hefty. When inserted there is a great sense of fullness, which I love.


All the glass Caterpillars in this line have different shaped heads, different curves, as well as several different colors to chose from. I chose the beautiful deep green with thin black stripes throughout. I love the color and the shape of the head and curve on this one is wonderful looking and feeling as well.

I believe, but am not sure, that the color choice I made has been around for a long time. The 1st clue to this is that none of the other Caterpillar Shafts look (to me anyway) quite as beautiful. The 2nd clue is that I got the very last one like this one and it has been sold out since. I really hope not. If you are wanting this particular one, I would suggest asking customer service about stocking it again. The 3rd clue I will tell you about later in this review.






Made of the finest medical grade borosilicate glass, which is designed to withstand extreme temperatures and physical shock without compromise to its structural integrity. Phallix states on the label that every step has been taken to ensure that this toy is safe. Including annealing; a time specific formula for baking and cooling that allows for it's extraordinary properties and durability far beyond that of ordinary glass. In addition, a polariscope is used to detect irregularities in the glass that are otherwise invisible to the naked eye. This beautifully rendered hand made functional erotic glass art should last you a lifetime.

This type of glass is naturally hygienic and cleaner than traditional materials. It is non-porous and hypo-allergenic. To clean you may wash with warm water and anti-bacterial soap. It may also be disinfected by boiling for 3 minutes or using a 10% bleach solution on it.


The length of my Caterpillar shaft is 7 1/4", with 6 3/4" being insertable. The thickest portion of the head is a tad over 5 3/4" in circumference and 2" in diameter. The smallest portion of the head; which is the tip is 3 1/2" in circumference and about 1" in diameter. Directly under the head is an interesting indention, which from there on down makes the shaft; which is 4 1/2" in circumference all the way down, including the hump. The flared base is 7" in circumference. The cone shaped hollow inside of the base will hold 2 of my fingertips and the outside of the base is strategically rounded so that holding with forefinger and thumb around it or by placing 2 forefingers inside and 2 thumbs outside is very comfortable to hold onto while thrusting or exploring. The base is also ideal in that it holds the shaft up for display if you like.

The angle of the head and the 2 1/2" curve length gives this shaft quite a bit of raised area in which to find the G-Spot; if rubbed against the front wall of my vagina.

I have often wondered if a G-Spot orgasm was just a myth since I have never had one before. Then I started thinking that I was simply not fortunate enough to have been born with one. Now that I have found this exquisitely shaped Caterpillar Shaft, however, I know what all the fuss is about!

I had planned on having this review ready and published by Sunday night at the latest. However something extraordinary happened. Upon my 1st insertion of this shaft, and feeling the upturned hump rubbing against the whole front of my vaginal wall. I felt instinctively that this would finally be the one that found my G-Spot. I had originally bought the Shaft to just try it and then add it to my collection of other beautiful glass sex toys.

I used it 6 more times this past weekend feeling that for once I was making some sort of headway. I tried it again once Monday and almost had it, but was rudely interrupted by life.


Ladies and gentlemen, I am well pleased to tell you that this morning of Tuesday, May 24, 2011 at approximately 6 AM Central time, (on the 9th use of Caterpillar Shaft) my elusive G-Spot was not only found but massaged in such a way that it most definitely WAS a religious experience. In all of my years; I have never experienced an orgasm of this quality or proportion. Vaginal contractions on a scale I have never felt before clutched and clamped onto the hard glass as well. Van Morrison was singing "Into the Mystic" on the radio. The smell of honeysuckle I had brought in from the day before and placed into a vase filled my nose with sweet fragrance.I will never ever forget 1 detail about this morning.
On top of all this joy, I think I almost squirted! My brain could not think logically at all by this time, and despite all of the wonderful advice I have been given here on Eden, I involuntarily stopped it because I thought I was going to pee. Next time there will be no stopping no matter what; pee or not!

Oh yes, the 3rd reason for suspecting that this Shaft by Phallix is an older model of the Caterpillar is the way it was packaged. When I opened the box sent to me by Edenfantasys, there inside was no tacky plastic packaging as I have received from Phallix in the past few months. There was no cheaply made silk bag either. There was simply a beautifully padded maroon colored drawstring bag! Inside the padded bag was the exquisite Caterpillar Shaft. I was so pleased! This is how Phallix must have packaged their glass toys before the day they decided that on top of us paying for an extremely expensive glass toy, that we must also pay for an expensive padded bag to go with it.
This is a great thing for me too; because this one will be my go to toy for years to come and I want it near me, in my bedroom and not on display.

The Caterpillar Shaft is by far my favorite glass toy. No matter what glass I may get in the future, it will always be the 1st one that found and pleased my G-Spot. It also taught me that I need this shape to orgasm by G-Spot stimulation. This will influence what toys I purchase in the future.
