Glass sex toys really used to freak me out.

Yeah, I said it. They did! I think I had an irrational fear that it would break inside of me. I was also carrying around a narrative that I only could truly enjoy vibrators, not dildos… which is hilarious.

The Unbound GEM Glass Dildo is only the second glass sex toy I’ve owned and now I’m hooked.

If you want to see the video review, check it out here:

Their packaging has a very femme-apple-esq vibe and I dig it.

Let’s talk about the specs:

  • Made with High-Grade Borosilicate Glass
  • Total Length: 8.5″, Insertable Length: 5″, Circumference: 4.75″
  • Dishwasher-safe (!!!!)
  • Good for vaginal, anal, and external massage
  • Great for temperature play (heat it up or freeze it!)
  • All lubes welcome (still make it glycerin-free!)
  • Package Includes: Dildo + Storage pouch

How to Use the Fun Factory MANTA

  1. Wash your GEM with toy cleaner or soap and water
  2. Grab your favorite glycerin-free lubricant (I highly recommend Sliquid’s Sassy!)
  3. Start by exploring how each end feels in your body
  4. See what feels the best… and keep doing it

Hint: If you’re also wanting clitoral stimulation, grab a vibrator to use on your clitoris while the GEM is inside!

Who May Enjoy This Toy, Sensations, & Ways to Use the Fun Factory MANTA

Who May Enjoy This Toy: Anyone who is looking to explore with glass toys, this is a great place to start.

Sensations: It’s so smooth and firm going in and being inside and presses all the right buttons.

Ways to Use Fun Factory MANTA:

  • Longevity – if cared for correctly and carefully they will last a lifetime
  • Non-porous
  • Rigid and firm structure for different types of orgasms
  • Temperature play: heat it up, cool it down, or use it at room temperature
  • Beautiful
  • Easy-to-clean

Important Note: I found that the smooth side felt best vaginally, while the bumpier side felt best anally.

Pros & Cons of the Fun Factory MANTA


  • Price. It’s incredibly affordable. ($34 and 10% off with my code RACHELW)
  • The versatility of usage (internal or external // temperature play or not)
  • It’s GORGEOUS and incredibly well-made
  • Intuitive: The toy is shaped intuitively, so when you insert it into the vagina or anus, it goes right to the spot you want
  • It’s beautiful to look at in your partner’s body


  • For newer users, it’s not entirely clear HOW to use this the best way. I’d love to see a guide with ideas on how to use it that comes with it

Overall Rating

To summarize, I can’t find anything wrong with this toy. It’s a perfect small-ish size glass dildo. You can’t beat the price and frankly, I think it’s a necessity in every home!

Overall: 5/5 stars
