OXBALLS MUSCLE – Long Cocksheath with ADJUSTFIT

Description
MUSCLE is an OXBALLS cocksheath designed to add substantial length and girth while providing mechanical support around both shaft and balls.
The sheath measures approximately 9 inches overall, with around 7.5 inches of usable external length depending on positioning.
Inside, the shaft channel extends approximately 5.5 inches and is lined with a series of soft ribs.
These ridges create continuous contact around the shaft and become particularly noticeable when MUSCLE is moved as a stroker.
The external head is thicker and more flared than the body of the sheath, creating a pronounced change in profile.
At the base, MUSCLE uses OXBALLS’ COCKSLING-2 architecture.
A main opening receives the shaft while a separate opening secures the balls, helping stabilize the sheath on the body rather than relying only on friction inside the channel.
MUSCLE includes a removable ADJUSTFIT insert.
The insert locks into grooves inside the channel and reduces available depth, allowing the sheath to accommodate different shaft lengths.
Its position can be changed according to the fit required.
The standard MUSCLE is made from flexTPR, a soft, rubbery and highly stretchable material.
Available including Black and Clear.

How to Use
Apply a generous amount of compatible lubricant inside the shaft channel and to the shaft.
Insert the shaft gradually into the sheath.
To adjust usable depth, position the ADJUSTFIT insert in one of the internal grooves before fitting MUSCLE.
Once the sheath is correctly positioned, stretch the base opening and pass the balls through the dedicated opening.
The sheath should remain secure without causing pain, numbness or unusual discoloration.
Remove immediately if significant discomfort occurs.

Care
Remove the ADJUSTFIT insert before cleaning.
Wash the sheath and insert thoroughly with warm soapy water and rinse well.
Pay particular attention to the internal ribs and grooves.
Allow both pieces to air dry completely before storage.
Store separately from other toys, preferably in a breathable cloth pouch.
