Ragproper Glass Flask Accessory Kit - Cleaning Set with Cleaning Brush, Silicone & Cork Lid Liners, Stainless Steel & Plastic Lids & Smooth Pour Funnels (Single Shot, 100mL)

I keep shine in my flask, which goes in my golf bag in the event my 18-handicap self makes a birdie. It's a beautiful flask, with a top that does not require me to also carry a pair of pliers in my bag to get it open. If you buy the flask (and I strongly suggest you do, if you have a need similar to mine to keep spirits in private), this is the optimal cleaning kit (and spare supplies) to get for it.

Excellent flask product 🥃. No leaks, and love the funnel for easy refill. I like that it’s glass, and protected with silicone body.

I actually funded the original flasks and over time, I had misplaced the funnels. I am so glad was able to not only get the funnels but replacement cork liners and the brush. SUPER WIN

Get this set . Worth the money.

Works as advertised

Nice to have because I think you will need these accessories since you will be using this one sturdy glass flask for a long time. No more rust worries from this flask.
