I've found these Crystal premium glass eggs are great beginner's glass Kegel exercisers. Why? Because they're light enough to wear while walking around the house for a few hours without the fear of them falling out. They're light enough for someone's first glass eggs for performing Kegel exercises, and are also great for partner or solo multiple toy play.

Even as I sit here writing this review, I have them inside me using the Wicked Ultra Chill lubricant for temperature 'play'. True, I'm not pleasuring myself, but sitting here is more pleasurable feeling with the coolness of the glass within me.

I've already used the Wicked Ultra Heat with other glass eggs, as I will with these, and always enjoy the variety glass eggs and toys permit the user when wearing or using them. So, you experienced Kegel exercisers, don't discount these, they can provide enjoyment for you too!

Because these eggs are so small and because of their funnel shape end, I found them easy to insert, even without lubricant. So if you do use lubricant, very little is needed!

As reported by EF Guide to Materials, borosilicate glass has the following properties:

Material safety is rated at 10.

Components:
A glass is an inorganic non-metallic material that does not have a crystalline structure. Such materials are said to be amorphous and are virtually solid liquids cooled at such a rate that crystals have not been able to form. Pyrex, a brand name for borosilicate glass, is made by adding boron into the mixture of sand, soda and ground lime.

Properties:
Pyrex is a hard material with a high chemical resistance and mechanical strength. The boron in Pyrex reduces any stress caused to the material due to temperature changes. It is less dense than ordinary glass, making it much more resistant to shattering and breaking as well. If it were to break, it would not shatter or splinter into tiny pieces but instead it would snap or break in large pieces. It retains temperature extremely well and requires only a little lube for a super-slippery effect.

Lubricants:
Silicone, water, oil

The eggs themselves remind me of small grocery store eggs that you buy by the dozen, but their glass nature and how you use them make them so much more inviting.

At 1 3/4" long x 1" at its widest diameter, these eggs are easy enough to slip inside even without lubricant. Their small size is great for beginner use and in partner play during intercourse. And because of their size, they're great not only during partner play but with other vibrating and non-vibrating dildos.

As with all toys without a wide tail, these are not to be used anally. It would only cause great embarrassment and discomfort.

These are great decorative objects, easily disguisable in a decorative dish of other assorted glass objects of various shapes and sizes. Because of their various intriguing designs and color varieties, they can fit easily with almost any room decor and no one would be the wiser.

These are great because these are the first glass eggs I was able to walk around the house with comfortably. They're light but efficient when standing, reminding you constantly of your Kegel muscles and tightening them. I like that they're easy to clean and portable to store anywhere.

They're great alone, and they're great in tandem or triplicate with other toys of your preference. I myself like to combine them with a silicone vibrating dildo, of which I have many, and vibrating silicone eggs. For me, they are best felt and enjoyed when I hear the deep rumbling within me making the sensation all that more real.

Because they are so small and light you will not hear them clattering together in mixed company or solo.

They are truly without a doubt Crystal Pink Persuasion because of their non-invasive and attractive design. In this instance, pretty does count!

As reported by the EF Material Guide, regarding hygiene and maintenance:

Glass is extremely smooth and nonporous. Easy to clean with soap/water or sex toy cleaner. Use condoms if sharing.

I clean them by soaking them for 15-20 minutes in hot tap water with anti-bacterial soap in my bathroom sink, right after a pleasure session. As with any toy, I run a EF Fantasy Cleaning wipe over them before each use. I always keep my toys, no matter their material make-up, separate, but erring on the side of caution is always preferred and advised.

For those of you who like to share their toys, I'm not one of them because I'm totally selfish with them and only use them with my Life partner. These eggs are shareable because they are both bleachable and boilable, even for use without a condom.

The package the Crystal glass eggs are sent in is attractive and non-offensive. While it does State CRYSTAL PREMIUM GLASS EGGS on the box, there are no erotic pictures or sexual references. I would easily wrap these up for a wedding or baby shower. A new bride and someone with a multi-wedding anniversary, as well as new mother, can always use these to stay in shape.

The package itself is 2 1/2" x 4 1/4" x 1 3/4" in measurement, with a 3/4" tab at the top as though it were to hang from a rack if you were to find them in a novelty store such as Spencer Gifts (my first go-to store for pleasure toys before Eden Fantasys).

I have the clear/pink glass eggs and found them quite attractive in the see-through egg-shaped windows in the package. The package does have cleaning instructions on the side but the print is easily readable and discreet.

Within the box, the eggs are enclosed in protective clear egg-shaped cups with a removable clear plastic cover. Also in the package are the nylon storage pouch and instructions. This was a blessing in disguise for me when I was first new to Kegel exercising. As much as I searched the internet on helpful instructions, I felt reassured that the manufacturer included simple one-sided instructions on an easy-to-read piece of paper, complete with a diagram.

Lastly, because they are delivered by Eden Fantasys, they are delivered in an unmarked box. OK, I sound like a commercial, but I enjoy and appreciate my privacy--as I'm sure you do too!

I've grown beyond these smaller eggs for strengthening my kegels but still find them enjoyable when sitting around the house, reviewing EF products, or just listening to music or watching TV. Besides just relaxing with them inside with a cooling or heating lubricant, I still enjoy them with my partner or other vibrating toys.

Another plus with these eggs, as with any glass toy, is that you can use any lubricant you prefer, whether water-, silicone- or oil-based. This gives these eggs a unique versatile use with the lubricant of your choice and preference.

These eggs were one of the first non-vibrating toys I use for partner play that my partner felt comfortable using. I love to experiment and try new things, but we are not all made alike. After 26 years of marriage, any partner can get hesitant to try new things. Mine was no different, but the small simple shape and attractive non-threatening nature of them was both comfortable for him and me when my "Love Tunnel" was being pleasured.
