Solid stainless steel. Secure flared base. Three levels of length and weight.
The Heavy Stainless Steel Butt Plugs are longtime HMO favorites for users who want the unmistakable feel of solid metal with real weight behind it.
All three sizes reach the same 1.5-inch maximum diameter, so the progression isn’t about getting progressively wider. Instead, you choose how much insertable length and stainless steel weight you want — from the compact 11-ounce Shorty to the substantial 22-ounce Extra Tall.
A narrow neck and broad flared base help the plug settle securely once positioned, while the smooth polished stainless steel surface gives you firm, consistent contact and easy cleanup.
⚙️ Why This Design Works
Same 1.5" maximum diameter
Every size provides the same basic fullness at the widest point
Three distinct weight levels
Choose 11 oz, 13 oz, or a substantial 22 oz depending on how much presence you want
Increasing insertable length
Progress from a compact 2.25" insertable profile up to the 4.75" Extra Tall
Narrow 9/16" neck
Helps the plug settle comfortably behind the sphincter once inserted
Secure flared base
Provides an important external stop for safer anal use and easier handling

🎯 Choosing Your Size
Shorty: the easiest place to begin if you want the 1.5" diameter without a lot of depth
Medium: adds a little more length and weight while keeping the same maximum diameter
Extra Tall: a substantial step up in both depth and weight, best suited to experienced users already comfortable with the diameter
🧼 Use & Care
Use plenty of lubricant and insert slowly with controlled pressure
Because solid stainless steel is firm and unyielding, never force insertion
For anal use, always keep the flared base outside the body
These plugs are about weight as much as fullness. The shared 1.5-inch diameter gives the line a consistent feel, while increasing length and mass let you choose just how much stainless steel presence you want.
