The four products share materials and sizing logic, but the head, the widest point
and the “event” on the way in are different. The specs above tell you the numbers;
the notes below tell you where those numbers sit on the shaft.
Flared head · Six sizes
The head is broad and flat, wider than the neck behind it — you take it as one
clear step, the neck lets your body close, then the middle opens wider than the
head did[reference:27]. Middle circumference runs 19.3 cm (7.6 in) on M and
27.5 cm (10.8 in) on XL[reference:28]. Pick by the circumference you already take,
not by length.

Rounded head · Deep folds · Three sizes
No single step on the way in: the rounded head slides through, a ring of fine
grain rolls past, and the deep folds take over while the shaft keeps widening
toward the balls[reference:29]. The widest point is the last part you take —
19.5 cm (7.7 in) on S, 29 cm (11.4 in) on L[reference:30]. For friction along
the full length rather than a knot.

Tilted head · Low knot · Four sizes
The shaft ahead of the knot stays close to one width, so it goes in easy; the
knot low on the shaft is where the stretch happens, popping through in one give
[reference:31]. Knot circumference runs 13.6 cm (5.4 in) on S to 25.2 cm (9.9 in)
on XL[reference:32]. The tilted head is for aiming — prostate or G-spot depending
on your anatomy[reference:33].

Human head · Swell + cinch · Four sizes
A human mushroom head, a full swell behind it, a cinch partway down, then a
second fill toward the root — a full stroke gives squeeze, then fill[reference:34].
Widest circumference runs 19.5 cm (7.7 in) on S to 32 cm (12.6 in) on XL
[reference:35]. It suits people who already take a human shape and want the width
to travel[reference:36].
