The bullet attachments are made of TPE. It has a rubbery scent and feels squishy, soft to the touch, and has a smooth texture.
What I found most appealing about these bullet attachments is the different shapes and textures of each attachment. The oval shaped attachment is ribbed, which adds a lot of stimulation to the nipples and the clitoris, or to the shaft or glands of the penis. The round attachment is quite adorable with its bulged hearts adding even more stimulation, and the seashell shaped attachment is nice because it is flat, which is perfect for vaginal penetration and for slapping it against the pleasure spots.
Because there are three different shapes and textures to choose from, it makes playing and experimenting with these attachments all the more fun. I was surprised at how large the attachments were, which made playing with them more pleasurable than if they were really tiny. I suppose the shape and size of the attachments also make them look innocent; they could easily be disguised as cat toys (in fact, my cat played with the round shaped one when I dropped it on the floor!). You can easily store the Purple Collection in your drawer or carry it around with you in your purse.
I would recommend lightly lubricating the holes inside of the bullet attachments; they are very small, so you have to stretch the holes to insert the bullet vibe in them. You need to only insert the bullet vibe an inch in; when you turn the power on, the bullet vibe shakes the entire attachment.
The control pack only requires two AA batteries. I was surprised that the vibe function was loud, but not as powerful as it should be. It was powerful enough to get me excited, but not enough to make me explode. I didn’t feel that the power of the vibe had any range. The vibe got louder, and a tad bit stronger, but not enough to really impress me much. The function of the vibe overall is pleasant and satisfactory, but nothing earth shattering.
You can wash the bullet vibe attachments with soap and water; be sure to take the attachments off of the bullet vibe before washing them. This isn’t a waterproof toy. Take out the batteries from the control pad compartment when wiping down the bullet vibe. The control pad unfortunately has a very cheap quality about it, so be careful with it when putting the batteries in or taking the batteries out.
