تم تصميم غمد Derek بطول 21.5 سم لتكثيف كل اختراق. بفضل تصميمه الواقعي وهيكله المرن، يزيد طول القضيب بمقدار 7.6 سم ويحسن محيطه بنسبة تصل إلى 35%. يحفز الملمس الخارجي ذو العروق والحشفة البارزة الشريكة، بينما يحيط الجزء الداخلي بالقضيب بثبات وراحة.

Madison★★★★★
Wasn't sure the elastic structure would feel natural, but it really does and stays put without slipping. The realistic design made the whole thing feel way less awkward than I expected.
Evelyn P.★★★★★
The 7.6 cm extra length is no joke, it genuinely makes a difference. The realistic design feels nice too, not plasticky at all.
Ella★★★★★
The elastic structure really surprised me, it stretches enough to feel secure without pinching. The extra 7.6 cm makes a noticeable difference and the circumference boost adds to it.
