Frequently Asked Questions
Q: What's the difference between SGE 400/3 and SGE 400/3BB? A: The SGE 400/3 has a silicone face seal. The SGE 400/3BB has a butyl rubber face seal, which provides superior resistance to chemical warfare agents (nerve agents, mustard gas) and meets stricter CBRN requirements. The 400/3BB is also slightly lighter. If you need maximum chemical protection, consider the 400/3BB version in our NBC Protective Kit.
Q: Why is butyl rubber better than silicone? A: Butyl rubber is impervious to nerve agents (sarin, VX), mustard gas, and other chemical warfare agents. Silicone provides good protection but doesn't meet the same military CBRN standards. Butyl rubber also has 200x better vapor resistance than natural rubber.
Q: What filters work with this mask? A: Any 40mm NATO threaded filter (EN148-1 / DIN 3183). We recommend our Multipurpose CBRN 40mm Filter ($54.95).
Q: Is this the same mask in the Tactical NBC Protective Kit? A: Yes. The Tactical NBC Protective Kit ($495.99) includes the SGE 400/3BB mask plus a filter, Tychem chemical suit, butyl gloves, overboots, and carry bag.

Fun read
Format: Kindle
I'm not really into mafia books but I love Roxy Collin's other series so I decided to give it a try. It had the same great romance, spice, swoon-worthy characters and exciting plot that are her signature. Arben was my favorite, although it was a bit sudden how quickly he changed from ignoring her to wanting to be pack. There were almost too many twists/layers of lies to keep track of but I'm looking forward to reading the other books.
The only thing that detracted from the story for me was the need for a bit more proofreading. It was mentioned that Kelly is a female and male at different points, leading me to think she changed her mind at some point about the character's gender but didn't go back and edit it to align in all places. Like another reviewer pointed out, step siblings are different than half siblings. They are incorrectly referred to as step siblings because they (allegedly) share the same biological dad. There are a few other typos as well but those aren't a big deal.

Stepbrothers, Secrets, and Sizzling Heat
Format: Kindle
Twisted Lies by Roxy Collins is a wild ride through family secrets, amnesia, and a steamy stepbrother romance. When Kelly discovers her life is built on lies, she ends up tangled with three alpha stepbrothers and an assassin who once helped her through a heat.
The tension? Off the charts!
The heat is real, and the complications are messy in the best way. Full of twists, secrets, and fated mates? You'll be hooked from page one!
Love omegaverse drama with a dash of taboo? This one's for you!

Good read
Format: Kindle
The book has some good twists and turns, but truthfully I was so confused on some things. It didn't have a good flow for me personally. Not sure if it's due to typos or using him/her wrongly, but I thought Kelly was both a guy and a girl. Actually I still don't know, and it made me incredibly frustrated. It would refer to Kelley as him or he, and then again in another part of the story as her she and sister. On to the next book, I hope there is some clarity and a smoother flow. This is a slow burn, and I just don't know how much I care for the Alphas yet. Idk if I recommend.

This is a story we’re a omega has been lied to by her mother and finds out that someone is slowing dieing. 3 alpha take the omega and feed her more lies so they can use her against her father so they can find their mate Kelly. This is a dark read and ends in a cliffhanger and so good.
