The plugs are made from a silky smooth, shiny, black PVC which may seem a little floppy at first, but the flex is actually just right and makes them comfortable enough to use for longer periods of time. Although it has a relatively low safety rating of "2", it's still phthalates free. Because it is porous, sharing is not recommended. Unfortunately, this type of material has a strong smell that takes a while to fade. All-in-all, it's a durable, easy-intro anal kit.
The design of these plugs is the best thing about them! Each plug is tapered, seamless, and has a rounded tip for easy insertion. Although limited to just the black color - without divulging the obvious reasons why - it's a good color to have, especially for a first timer who may be a little self-conscious about anal play.
The largest/widest portion to be concerned with is located about midway down each plug, with the diameters ranging from 3/4 to 1-3/4 inches, respectively. The heights are 5, 5-1/2, and 7-1/4 inches, respectively, with the insertable portion of each being approximately 2 inches less due to the flared suction cup bases. Only the small plug is completely smooth for the entire insertable portion and could be compared to sticking a finger in the anus. The medium and largest plugs both have a few 'speed bumps' below the widest portion, which may add some extra sensation (depending on the user's sensitivity level) once the bulk of the toy is in and if the user chooses to do a little light poking around.
Although not marketed to be used in a harness, the largest plug 'could' possibly fit in select harnesses, such as the Joque by Sportsheets. Ideally though, the plugs are meant to be used independently or suctioned on to a smooth surface (shower, tub, table, etc...). The quality of the suction cup bases is good, with tight seals that hold the toys in place. Any type of anal insertion takes practice; however this process can be less frustrating by holding the toy closer to or well above the thicker middle section and carefully guiding it in. It's not like holding a dildo/vibrator at the base and getting it in on the first try.
Either a silicone or water-based lube can be used. Warm-water and antibacterial soap is the best cleaning method. The clamshell packaging makes for good storage, as each plug has a separate compartment to sit in.
This product is manufactured in the USA. The 10 x 10 inch plastic clamshell packaging has a clothed picture of Wendy Williams, pornstar (not the talk show host) on the paper insert, which highlights the features of the plugs.
Because they are very flexible, it didn't feel like something stiff was poking around in my rear. I could sit, stand, lie down very easily with the smallest toy discreetly concealed in my anus. This became more difficult as the sizes increased, so I don't think I'd recommend wearing the largest one out in public.
