Reddit reviews 6 Syringes with Long Needles for refilling with Refillable Cartridges and Continuous Ink Supply System CISS

The ones I got on Amazon were 6 for 3.98$ and sold for use with refilling printer cartridges. They are 10ml which is a little big -- but they're great.

The blunt metal syringe is removable which is nice, and 10ml is enough you can "pressure burst" into tight places in demonstrator pens to remove ink that won't budge without pressure.

Ooooh never thought of those. I just use these ink cartridge syringes, but I keep losing them lol, so it might be good to get that 100 pack haha.

Nice work, moss is the hardest imo. Keeping them moist enough, especially in a non-closed environment is tricky to say the least!

I notice you seem to be watering with a spray bottle... one thing I've found handy for avoiding water on the glass is to water with a long needled syringe...

Makes sense. Something like these little guys?

You might consider getting a cheap set of blunt syringes instead (like these). With a syringe, you can easily empty a Preppy cartridge and refill it with any ink you want. I have refilled cartridges many, many times.

Try this one! https://www.amazon.com/Syringes-refilling-Refillable-Cartridges-Continuous/dp/B006DN11DS

I haven't thought out a price and won't have pics on hand until after work, but I think this would fit the bill and your price point:

• 5 or so unused and barely used Jinhao 599s
  
  
• 5 packs of 7 different colors international cartridges
  
  
• A nearly full bottle of Waterman Mysterious Blue
  
• A couple of syringes for eyedroppers
  
• A couple of B5 dotted notebooks
  
• A faux leather pen roll

You really aren't going to need a set a needles hiking in Tibet. You will need toilet paper, water purification, and some kind of anti-diuretic pills. Also like any alpine type hike I'd bring a climbing rated helmet because some of the ascents/descents can be very steep with the real risk of rock fall. Ditto for hiking any unkept portions of the great wall.

On a side note you can totally buy hypodermics on Amazon.
