Why buy this
Buy this when the door gap gives access to the thumbturn
Some commercial double doors leave a narrow route to the internal thumbturn. A shaped reach-through tool lets a trained user operate the thumbturn without attacking the cylinder.
Reach-through method
Designed for suitable gaps between double doors.
Thumbturn focus
Targets the internal thumbturn rather than the keyway.
Non-destructive route
Useful when authorised access can be achieved without drilling or pulling.
Use route
How to assess the door first
Check the door gap, thumbturn position, and authorisation before using the tool. Work slowly so the tool does not scratch surfaces or bind in the gap.
- Confirm the gap and thumbturn layout.
- Work gently to avoid door damage.
- Use only for authorised entry work.
Helpful next step: bypass tools.

The Lazy Makeup Day MVP
Size: 1.7 Fl Oz (Pack of 1)
This has become my easy low-maintenance face day product. It gives just enough tint to even things out while still giving solid SPF coverage, so I can skip foundation without feeling totally bare-faced. The finish feels lightweight, my skin stays comfortable all day, and the color blended into my skin way better than I expected from a “universal” tint.

Overall good aesthetic result for mineral sunscreen, but some downsides
Size: 1.7 Fl Oz (Pack of 1)
It is quite good overall, it blends in perfectly to my medium-light warm tone skin. There is no white tint. It seems effective in terms of SFP and doesn't leave a greasy or heavy feel, ends up looking lightly glowy but reasonably dry to the touch. I'm not sure you'd want to apply it thick enough to substitute for foundation.
What I don't like
- Like makeup the color can rub off on clothes etc.
- Doesn't seem to reapply very well, leads to pilling, and also rubbing my face at all leads to pilling. It's very "don't touch it again after you applied once"
- Quite hard to remove with normal cleanser, I think I might need to remove it with oil or something?

Way too heavy & greasy for combination skin
Size: 1.7 Fl Oz (Pack of 1)
Ugh this tinted sunscreen is such a let-down. I was excited to find an option that's a mineral sunscreen, with tinting that's supposed to work for all skin tones, is made with non-comedogenic ingredients, and is a more reasonable price than what my old tinted sunscreen now costs. I saw mixed reviews on the greasiness / heaviness of this sunscreen, but decided to give it a try, especially because I have combo skin that gets pretty dry in the winter... but wish I had listened to the people who said this is overwhelmingly thick.
Pros: the tint works fairly well for my light-to-medium warm-toned skin (although you can see in my video it doesn't blend at all well with my hand's skin tone... so can't imagine this will be universal), it doesn't irritate my combination skin that can be very sensitive, and hasn't blocked my pores.
Cons: This feels like I'm smearing peanut butter on my face - it is such a thick and oily consistency. I have combination skin, with some areas that are especially dry right now in a northern winter climate... but this is not what I would call "moisturizing" - it's greasiness that is impossible to rub in, doesn’t dry down, and instead just sits on the skin (and I'm not even using close to the amount of sunscreen you're supposed to in order to get the true SPF coverage). I use tinted sunscreen to replace the need for a BB cream or foundation, and this unfortunately would never be appropriate for everyday wear.
