Reusable Empty Caulk Tube - REFILLABLE CAULKING Cartridge 10 oz. - 3 Pack

It's a good idea to cut a ring of plastic to use as a tool to get the plunger out. For the smaller size I used a piece of house vac tube. Once cut it can be placed back in and then the plunger can be squeezed out. The result is a mess with all the drywall compound, but it helps get things in the gaps.

I use these for drywall repair to ceilings. Makes it easier to match the knock down texture in small areas to the rest of the ceiling.

Love these they work great with grout in hard to reach places

Great reusable caulking tubes that can be filled with a variety of materials. I used grout in one of mine to regrout the tile in my bathroom shower. Worked great and was a lot quicker and less messy than using a putty knife or trowel to apply the grout mixture.

Worked well a couple times then split at the head cap. Ended up replacing with a brand without a removable head.

Used these to spread glue on vinyl tiles. Fast , easy and no mess!

I tried using these with a wood filler compund. Both of the trials I had, the tube bursted in my hands. Right next to the writing that said "Patent Pending". The quality of the material is very questionable.On another note, the tip of the tube is thicker than a regular tube due to the overhead. The manufacturers kept the volume same as regular same sized tubes, thus the resulting tube ends up being slightly thicker. It didn't fit in one of my caulking guns, so I had to use an open ended caulk gun.

Worked as expected.
