2" x 1/2" and a 1/4" thick with a 3/16" hole. Available in assorted colors only. Red, Orange, Yellow, Green, Blue and Purple. Perfect for small bird or medium birds who are timid chewers. The holes are also perfect for Polly Rope, Light and Medium Hemp, Cord, Plastic Lacing or 1/16" and 1/8" Round Leather Laces. These 1/4" Balsa Slats are not cut to their standard size or the hole is not drilled in the center. We doubt your birds will notice the difference.
