B-VIBE產品中最小的塞（直徑2.2CM），適合剛入門開始接觸的新手。雖然店員認為初頭淺嘗最佳必定是手指加手套不用錢，但質素好的工具也令探索過程事半功倍。
整個系列尺寸齊全，由左至右，從小到大，順序排列。
頂部是易於進入圓錐形設計，軀干位置卻是稀有的直身柱體形，如此直徑均一，容易量度，可以準確符合開發中的最佳尺寸，不會強行撐開門戶。頸部只有一厘米粗，不會撐大門口，而且可因應姿勢彎曲，在站立時、坐下時還是行走時減低異物感。
每個型號內建負重，會小幅度郁動。重量是訓練入口的緊緻度和咬合力的必要原素。平常行走時使用會被帶動而在直腸管道中上下滑動。而這種微刺激會令肛門括約肌反射性收縮，就像舉啞鈴一樣有鍛練效果。
