AMSTERDAM – In response to customer requests, male pleasure products manufacturer Velv’Or has added four new sizes to its JNaja line.

It seems the League of EnRinged Gentlemen — an unofficial brotherhood of men who consider cock rings an essential part of their wardrobe — found JNaja’s previous diameter range of 45mm, 50mm and 55mm inadequate. Velv’Or complied with the Gentlemen’s requests and added 35mm, 40mm, 47.5mm and 52.5mm sizes to the collection.

Velv’Or also made a small design change to increase comfort: The logo has been moved from inside the perineum massage point to the outside of the device.

JNaja is a rigid, ergonomically designed cock ring designed to provide the wearer with comfort and stimulation beyond what is obtainable from more conventional O-rings and tongue-style rings.

“The ergonomic design makes wearing the JNaja way more comfortable,” said designer Jelle. “Many of the current EnRinged Gentlemen wear it 24/7 and own multiple sizes and colors.

“Velv’Or advises a not too tight version for all-day wearing pleasure and a tighter fit while enjoying a Penis Workout of the Day or Sex Workout of the Day.”

JNaja is available in standard black, red and white in addition to fashionable colors including blue and yellow.
