Big Teeth Golf Mallet Square Putter Cover with Magnetic Closure (PU Leather) – Fits Spider Tour-style heads

If your putter spends more time knocking about in your bag than it does on the green, a dedicated cover can be surprisingly important. The Big Teeth Golf Mallet Square Putter Cover is a PU leather headcover with a magnetic closure, made to protect a square mallet-style putter head during transport.

On paper, it’s a practical, everyday accessory: easy on and off thanks to the magnet, with an outer that’s described as waterproof and resistant to dust, plus a thick, soft interior to help prevent knocks and dents.

What it is and what problem it solves

This is a putter headcover for a mallet putter with a square-ish head shape. The core job is simple: shielding the metal head from scuffs, dings and minor impacts while the club is bouncing around inside your golf bag.

If you’ve ever pulled a putter out to find a few unwanted marks after a round, or you’re the sort of golfer who irons out small things (organisation, kit protection, keeping gear looking decent), you’ll get the point quickly.

The essentials: magnetic closure and protection

The standout feature is the strong magnetic closure. The idea is that it should be straightforward to put on and take off, while still staying in place during play and movement—so it isn’t supposed to slide off the head.

The outer material is described as synthetic leather (PU leather) and, importantly for real-world bag conditions, it’s claimed to be waterproof and resistant to dust. That means it’s less likely to get soaking-stained after damp rounds, and it should help keep grime away from the head.

Inside, there’s a thick, soft lining. That’s the part you’ll notice when the club is travelling—extra cushioning to reduce denting from contact with other clubs or hard bag components.

Where it fits (and where it doesn’t)

The cover is designed to fit most square mallet putters. The description specifically calls out examples such as “Spider X / Spider EX”, so it’s clearly aimed at that style of head rather than a narrow blade or a very different mallet shape.

Worth considering if you have a square mallet head and you just want something that does the basics reliably—easy closure, head protection, and a clean look in your bag.

It might not be for you if your putter head shape is significantly outside that square mallet category, or if you’re expecting a universal fit that works perfectly on every conceivable design. With headcovers, a bit of mismatch can be the difference between a secure fit and one that feels loose.

What you’ll notice during use

A magnetic closure is usually one of those features you either love immediately or you don’t really care about. Here, the selling point is convenience: you can get the cover on and off quickly without wrestling straps.

In day-to-day use, that matters when you’re moving fast between holes, or when you’re organising your bag in wind and rain. For a small kit item, it’s a very tangible improvement over covers that take longer to align or fasten.

The interior padding should also make a difference over time, especially if you’re hard on your kit—treating your bag like it’s going to get knocked about on the way to the course.

What matters most before you buy

Before you commit, it’s worth checking two things:

• Your putter’s head shape: this is for square mallet style heads, with “Spider” X/EX mentioned in the description.
• Your expectations of fit: the product is aimed at “most” square mallet models, but “most” still leaves room for exceptions.

Mini FAQ

Is the cover easy to remove and replace?

The description highlights a strong magnetic closure designed to make it easy to put on and take off.

Is it meant to protect against water and dust?

The outer PU leather is described as waterproof and resistant to dust, which should help in damp conditions and dusty storage.

Will it stop the cover sliding off?

It’s described as having a strong magnetic closure that should prevent the headcover from sliding off the putter head.

What kind of putters is it designed for?

It’s intended for square mallet putter heads, with examples given including Spider X and Spider EX.

Is it worth it?

It’s a solid pick if you own a square mallet putter and want a practical PU leather headcover that’s designed around quick, magnetic access, plus cushioned protection for the head during travel. If you care about keeping your putter looking tidy and you regularly throw your bag in and out of cars or trolleys, this kind of headcover makes day-to-day sense.

You may want to skip it if your putter head is not in that square mallet category, because the description focuses on that specific style of head. And while the materials are described as waterproof and dust-resistant, remember that no cover replaces careful storage—if your kit is left to soak for long periods, protection claims won’t do miracles.
