Poorly constructed Mexican knock-offs of large and strong American dildos. Can be identified by their mustard brown appearance with strange
white blotches (indicative of either a
poor paint job or some "factory testing" before shipping?) and by bending the mildo across the shaft, checking for
stress fractures or tears. Inferior-quality dildos
will tear down the length of the shaft, causing irritation and discomfort during use and they may even break off into the vagina or anus.
Just stick to American made dildos from mom & pop sex shops and you should be OK.
