Quality coiling rods

These coiling rods are very well made. Heavy and very nicely machined. Feel substantial in the hand and are big enough to be easy to use and small enough when fitting the coils into any of my atties. The set contains all of the sizes I use regularly. Well worth the asking price


Everything about this mod is great. Feels great in the hand. Hits really well and the finish is fantastic. It's never out my hand. Well done your smashed it with this

Great mod

First mod from here,isn’t my last though. Fits the hand perfect and is fantastic with my kayfun lite. So much so,I ordered another one last night!

SQ 510 o-rings

Just picked up pack of these when i ordered my SQ mod for future spares.


Amazing quality, and fast service, as usual. Fits perfect, and brought my old mod back to life. Made it work just like new. Thanks!

Doesn't disappoint, delicious !!!

I've wanted to try Bule Bolu for years, it's always either out of stock or not for sale on many online stores.
I finally found it in stock on signature tips, it's definitely a must try,
A delicious creamy, banana, pound cake that leaves a delicious aftertaste that's both unique and more'ish.!
It's not cheap but it's worth paying £20 for a 100mls.
I will be buying again for sure.!
Great service from signature tips, many thanks.

Squonk Bottle

Purchased few of these for new mod as spares. Perfect.

SQ217 squonk

Great little squonker, nice feel in hand, easy to remove bottle for filling (I leave the tube attached to mod then feed the tube back into the filled bottle). Costly but worth it in my opinion.
