SNUG PLUG系列最大的5號塞，直徑5.1cm，重量350g。基本上已經大於或接近真人的最大尺寸，幾乎任何人未經訓練不能直接用，強硬進入會裂。請量力而為。
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。
If you're nearing the end of your advanced anal journey, the Snug Plug 5 is as large as it gets- it's the Goliath of our weighted butt plug series.
The chances are that you're already familiar with or even own the Snug Plug 4. What separates the two? The Snug Plug 5 weighs 350 grams (vs. the 257 grams of Snug Plug 4) and is an inch bigger at 6.3".
Like all Snug Plugs, this XL version features everything that anal play fans have come around to love! And that's internal weights for intense stimulation, smooth silicone for maximum comfort & prolonged wear, and intelligent design for easy insertion and removal.
