Dowel Centers, Stainless Steel Dowel Center Transfer Plugs 10PCS with 5 Sizes of 1/4" 3/8" 5/16" 7/16" 1/2" Dowel Centering Pins Joinery Accessories -by MinliGUY Woodworking Tool

First off, these come in sets of pairs, so if you want 4 of the same size, you'll need 2 sets. No surprises there.What I was pleased with is that they came in a neat little organizer, that is big enough to hold at least 2 sets. (See pictures)Also, they are SOLID, and MACHINED, not some pot metal casting with a hollow base. With care, these should be a buy once item.I was a bit concerned about the price, but given the quality of the received product, they are a great value.Looking forward to using them on many projects in the future.

High quality, nice storage case, very happy with product!

I'm a beginner and basically do woodworking as a hobby. I got to say these pin centers saved my wood projects from many misalignments. They are strong and effective. Definetely would buy again.

Works great.

I used these as soon as I received them to help align a couple pieces of wood and they made the job 100% better. I also used them for some barrel hinges and again, they made it so the box lid fit absolutely perfect. The pins fit snugly in the holes I drilled and that is not a small thing. If the pins are slightly off they are no good. I wish I bought these years ago

Nice, small plastic storage box that fits in my small toolbox box drawers. The product quality is great, and will work for many years..

Indespensible for joinery if you are beginning woodworking.

Quite happy with purchase. This set support dowel pin use cases where one needs up to four pins simultaneously.
