Sigara Brand 3ct Cork Pipe Knocker

Arrived on time and as described. The adhesive backing on these knockers is surprisingly strong. I had bought mine for a project, & ended up taking the adhesive off & using craft glue for adhering and it worked wonderfully. I attached one of these knockers to a 1950's glass ashtray and am very happy with the results. Since its a 3 pack I also have back-ups. I would buy again though if ever necessary

The knocker is a decent size and fit well into my ashtray. The adhesive on the bottom secured it nicely. It has been in place for about two weeks now, with no problems. I've used it to knock ashes out of pipes at least a dozen times, and it is still stuck to the ashtray.

adhesive never works with these things so one star off. but we'll priced and for three in a bag I'm happy. I just use crazy glue to attach to ashtray or bowl and it stays strong.

Item as described

I have no problem with the cork quality and the workmanship/design of the knockers... I just wish they could be a bit bigger. They are very small to me as I thought they'd be a lot bigger from the on site product picture (but you can never judge size from a picture.) I'm thinking the size is because they have some adhesive on the bottom and you are supposed to stick them into a glass ashtray and hit the knocker sharply with the edge of your pipe (or so I've seen on youtube?). But I wanted to use mine by hand, the opposite, and hit the pipe with the knocker. But being so small it's hard to pack a good enough wallop to dislodge all the stubborn remains of your last bowl. Although it does an adequate enough job that I'll keep using them. And someday maybe I'll find a glass ashtray to stick them in and use them correctly (although I'm sure there is no right or wrong way to use them) also no paperwork came with the product so I guess it's understood that how to use them is already known?! Or heck- you can do what you want with them... it's not rocket surgery and there are no cork knocker police out there.

I hesitated to buy these because I wasn't sure how I was going to affix them to my ash tray, but they all came pre glued. I just peeled off the paper on the bottom and it stuck lie a charm. PERFECT

Works as expected. No issues to date.

Nice purchase. I am able to use my own ashtrays with these corks. Less expensive & provided same results
