it depends on what your qualifications for a "green" toy are!!

if you just mean rechargeable toys/wooden toys/toys that can be disposed of without releasing as many bad chemicals into the environment (LOL jelly) then...yes! quite.

rechargeable toys like the mimi and the tango are often stronger than traditionally battery-powered equivalents and sustainably grown wooden sex toys such as those by nobessence are usually well-designed and as effective as other dildos in practice!

someone else will likely come along with a more detailed/knowledgeable comparison between "green" and "nongreen" sex toys but...i think for the most part as long as you buy things of comprable quality in terms of design and such green toys are just as pleasurable as others!
